With the equation caco3 2hcl cacl2 h2o co2 hypotheses a reaction occurs when particles collide.
Marble chips and hydrochloric acid experiment equation.
Marble chips and hydrochloric acid planning aim to find if changing the concentration of an acid will increase or decrease the rate of the reaction when marble is dissolved in hydrochloric acid.
I marble chips are made from calcium carbonate hydrochloric acid calcium carbonate calcium chloride water carbon dioxideii the rate of reaction can be increased by increasing the concentration of hydrochloric acid which is the limiting factor in this equation.
Plugged in scientific scales and weighed out 1g of marble chips for each test tube.
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.
Marble chips placed onto pieces of paper.
Hydrochloric acid to react with the marble chips independent variable marble chips to react with the acid dependent variable stopwatch to accurately time the experiment spatula to handle the marble chips measuring cylinder to precisely measure out different concentrations of hydryochloric acid electric balance to measure the mass g of the marble chips bung.
This can be done by having the reaction take place.
Marble chips calcium carbonate caco 3 react with hydrochloric acid hcl to produce carbon dioxide gas.
Calcium chloride solution is also formed.
Using the apparatus shown the change in mass of carbon dioxide can be measure with time.
In the investigation i am going to find out how the surface area affects the rate of reaction by measuring the amount of gas produced and weight loss in a reaction between small large pieces of marble chips calcium carbonate and hydrochloric acid per minute.
The rate of this reaction can be changed by changing the size of the marble chips.
Caco3 2hcl h2o co2 this is the reaction we will be investigating.
2 h cl aq ca co 3 s ca cl 2 aq co 2 g h 2 o l the rate of this reaction can be measured by looking at the rate at which the product carbon dioxide gas is formed.
Marble chips react with dilute hydrochloric acid to produce carbon dioxide gas.
This process is based on random particle movement.
Investigating the rate of reaction between marble chips calcium carbonate and hydrochloric acid aim.
An investigation of the reaction between marble chips and hydrochloric acid.
