Investigating the rate of reaction between marble chips and hcl
The rate of reaction between hydrochloric acid and marble chips essay - the rate of reaction between hydrochloric acid and marble chips plan in this experiment, i will be investigating the rate of the reaction between hydrochloric acid (hcl) and marble chips. However, barrans (2012) highlights that the reaction rate between magnesium metal and hcl follows first order kinetics this is because the hydrogen ions (h+) from the acid i have a large binding surface on magnesium metal but later, the surface area diminishes due to other factors in the reaction. Students follow the rate of reaction between magnesium and the acid, by measuring the amount of gas produced at 10 second intervals 3 cm of magnesium ribbon typically has a mass of 004 g and yields 40 cm 3 of hydrogen when reacted with excess acid 50 cm 3 of 1m hydrochloric acid is a six-fold excess of acid.
The rate of reaction between the marble and hydrochloric acid particles was much faster with the powder explain why -the (marble) powder has a larger surface area than the (marble) chips.

To observe the effect of surface area (particle size) on the rate of reaction between marble chips (calcium carbonate) and hcl 3bto observe the effect of surface area (particle size) on the rate of reaction between magnesium ribbon and hydrochloric acid. An investigation into the factors affecting the rate of the reaction between calcium carbonate and hydrochloric acid biology investigation: investigating the effect of catalase concentration on the speed of reaction with hydrogen peroxide.
Investigation of the reaction between marble chips & dilute hydrochloric acid i predict the higher the concentration of hydrochloric acid, faster the reaction rate and more carbon dioxide will be produced as the time increases this is due to the collision theory investigating the rate of reaction - sodium thiosulphate and. A sample of marble chips is weighed on an analytical balance the chips are poured into a beaker, and nitric acid solution containing bromphenol blue indicator is added when the beaker is viewed two hours later, bubbles can be seen and a color change is evident, suggesting that a chemical reaction has taken place. - an investigation into how changing one variable influences the rate of reaction between marble chips and dilute hydrochloric acid planning section when dilute hydrochloric acid reacts with marble chips the following reactions occurs: caco3 + 2hcl = h2o + co2 this is the reaction we will be investigating. In this reaction you will observe the reaction between the reaction between calcium carbonate and hydrochloric acid, a common chemistry reaction begin by writing a chemical equation for this reaction and include the states of each reactant and product. In this experiment i shall be investigating how temperature affects the rate of reaction rates of reaction the factors that affect the rate of reaction are temperature, surface area, concentration, catalysts, light and pressure.
A demonstration of the procedure for investigating the effect of concentration on the reaction between hydrochloric acid and calcium carbonate (marble chips) the gas syringe method is used. Demonstrating rates of reactions is easily done in the classroom, but too often teachers resort to using the reaction between marble chips and hydrochloric acid the oxidation of luminol makes for a welcome change as a demonstration, or for a class-based investigation. Gcse chemistry coursework: investigating the rate of a reaction your task is to plan, and carry out, an experiment to discover how to change the rate the reaction between sodium thiosulphate solution and dilute hydrochloric acid.
Rates of reaction what is the effect of increasing the surface area of a solid on the rate of a chemical reaction a solid that is present in a solution can only react when particles collide with the surface of the solid if the area of the solid surface is made bigger then more particles can collide with it per second and the rate of the chemical reaction increases. An investigation on how different concentrations of one type of reactant (hydrochloric acid) affect the rate of reaction between marble chips (caco3) and hydrochloric acid (hcl) by measuring the volume of carbon dioxide (co2) produced. Extended experimental investigation: reaction rate to investigate the effect of reactant concentration and surface area on the rate of the reaction between marble chips and hydrochloric acid and to determine the order of reaction rate (mg/s) small chips 15m hcl large chips 15m hcl small chips 3m hcl large chips 3m hcl 0 – 15 . Chemistry (2007) sample assessment instrument extended experimental investigation: reaction rate this sample has been compiled by the qsa to help teachers plan and develop assessment.
Investigating the rate of reaction between marble chips and hcl
You repeat the experiment with different concentrations of hydrochloric acid to see its effect on the rate-speed of the reaction between hydrochloric acid and limestone/marble chips-powder. Rates of reaction: hydrochloric acid & marble chips the experiment the aim of this experiment is to find out how different variables affect the rate at which the reaction between marble chips (caco ) and. Page 2 q1marble chips are mainly calcium carbonate (caco 3) a student investigated the rate of reaction between marble chips and hydrochloric acid (hcl.
- An example often used when demonstrating chemical reactions is the reaction between hydrochloric acid and calcium carbonate: caco 3(s) + 2hcl (aq) cacl 2(s) + h 2 o (l) + co 2(g) the rate of reaction can be altered by changing the size of the calcium carbonate chips or the concentration of the acid.
- The rate of a reaction is found by measuring the amount of a reactant look at this reaction: magnesium 1 hydrochloric acid magnesium chloride 1 hydrogen mg (s) 1 2hcl (aq) mgcl 2 (aq) 1 h 2 (g) here hydrogen is the easiest substance to measure, because it is the only gas in the reaction it bubbles off and can be collected in a gas syringe.
- You repeat the experiment with different particle sizes to vary the surface area and its effect on the rate-speed of the reaction between hydrochloric acid and limestone/marble chips-powder you need a variety of limestone particle sizes eg marble chips - lumps, granules and fine limestone powder.
In section z the reaction has stopped, as one of the reactants (marble chips or hcl) has run out, so there are no particles left to react (c) when more concentrated hydrochloric acid is used, the reaction is faster. Investigating the rate of reaction between marble chips (calcium carbonate) and hydrochloric acid aim 1111 words | 5 pages investigating the rate of reaction between marble chips (calcium carbonate) and hydrochloric acid aim. Investigation into the effect of one factor on the rate of reaction using a gas collection method investigation into the effect of one factor on the rate of reaction between dilute hydrochloric acid and sodium thiosulfate.
