Marble Chips And Hydrochloric Acid Equation

Marble chips calcium carbonate caco 3 react with hydrochloric acid hcl to produce carbon dioxide gas.

Marble chips and hydrochloric acid equation.

Immediately connect the gas syringe and start a stop clock. An investigation of the reaction between marble chips and hydrochloric acid. Hcl calcium carbonate calcium chloride carbon dioxide water. With the equation caco3 2hcl cacl2 h2o co2 hypotheses a reaction occurs when particles collide.

Marble chips react with dilute hydrochloric acid to produce carbon dioxide gas. 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. The rate of this reaction can be measured by looking at the rate at which the product carbon dioxide gas is formed. 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 stand to hold up the measuring cylinder. Investigating the rate of reaction between marble chips calcium carbonate and hydrochloric acid aim. Calcium chloride solution is also formed. 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.

Using a measuring cylinder add 50 cm 3 of dilute hydrochloric acid to a conical flask. 2hcl aq caco 3 s cacl 2 aq co 2 g h 2 o l. How can the rate of the reaction between calcium carbonate and dilute hydrochloric acid be measured. Label this line a.

Being alkaline it reacts with hydrochloric acid to produce calcium chloride water and carbon dioxide. Add 0 4 g of calcium carbonate to the flask. Using the apparatus shown the change in mass of carbon dioxide can be measure with time. The rate of this reaction can be changed by changing the size of the marble chips.

Marble chips are mostly made up of calcium carbonate which is a alkaline compound. The variables that i shall be changing will be the concentration of hydrochloric acid and water. A conical flask contains the marble chips hydrochloric acid and the water that will make the reaction. 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.
