Marble Chips And Hydrochloric Acid Equation

An investigation of the reaction between marble chips and hydrochloric acid.

Marble chips and hydrochloric acid equation.

Being alkaline it reacts with hydrochloric acid to produce calcium chloride water and carbon dioxide. 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. Marble chips calcium carbonate caco 3 react with hydrochloric acid hcl to produce carbon dioxide gas.

Label this line a. This process is based on random particle movement. The variables that i shall be changing will be the concentration of hydrochloric acid and water. 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.

Calcium chloride solution is also formed. Using a measuring cylinder add 50 cm 3 of dilute hydrochloric acid to a conical flask. Immediately connect the gas syringe and start a stop clock. 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.

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. A stand to hold up the measuring cylinder. A conical flask contains the marble chips hydrochloric acid and the water that will make the reaction.

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. Hcl calcium carbonate calcium chloride carbon dioxide water. How can the rate of the reaction between calcium carbonate and dilute hydrochloric acid be measured. 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.

2hcl aq caco 3 s cacl 2 aq co 2 g h 2 o l. Using the apparatus shown the change in mass of carbon dioxide can be measure with time. A tube to connect the conical flask to the measuring cylinder. Add 0 4 g of calcium carbonate to the flask.
