Marble chips are mostly made up of calcium carbonate which is a alkaline compound.
Marble chips and hydrochloric acid equation. With the equation caco3 2hcl cacl2 h2o co2 hypotheses a reaction occurs when particles collide. A stand to hold up the measuring cylinder. Hcl calcium carbonate calcium chloride carbon dioxide water. Marble chips react with dilute hydrochloric acid to produce carbon dioxide gas.
2 marks 9 4 explain in terms of particles how and why the rate of reaction changes during the reaction of calcium carbonate with hydrochloric acid. A tube to connect the conical flask to the measuring cylinder. Being alkaline it reacts with hydrochloric acid to produce calcium chloride water and carbon dioxide. The rate of this reaction can be changed by changing the size of the marble chips.
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. A conical flask contains the marble chips hydrochloric acid and the water that will make the reaction. The rate of this reaction can be measured by looking at the rate at which the product carbon dioxide gas is formed. Marble chips calcium carbonate caco 3 react with hydrochloric acid hcl to produce carbon dioxide gas.
Using a measuring cylinder add 50 cm 3 of dilute hydrochloric acid to a conical flask. Using the apparatus shown the change in mass of carbon dioxide can be measure with time. 2hcl aq caco 3 s cacl 2 aq co 2 g h 2 o l. Investigating the rate of reaction between marble chips calcium carbonate and hydrochloric acid aim.
Label this line a. Calcium chloride solution is also formed. How can the rate of the reaction between calcium carbonate and dilute hydrochloric acid be measured. The variables that i shall be changing will be the concentration of hydrochloric acid and water.
Immediately connect the gas syringe and start a stop clock. 9 3 sketch a line on the grid in figure 10 to show the results you would expect if the experiment was repeated using 20 g of smaller marble chips. 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. This process is based on random particle movement.
