Marble Chips And Hydrochloric Acid 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.

Marble chips and hydrochloric acid equation.

Add 0 4 g of calcium carbonate to the flask. Label this line a. 2hcl aq caco 3 s cacl 2 aq co 2 g h 2 o l. Calcium chloride solution is also formed.

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. An investigation of the reaction between marble chips and hydrochloric acid. A stand to hold up the measuring cylinder.

Marble chips are mostly made up of calcium carbonate which is a alkaline compound. The rate of this reaction can be changed by changing the size of the marble chips. Being alkaline it reacts with hydrochloric acid to produce calcium chloride water and carbon dioxide. Investigating the rate of reaction between marble chips calcium carbonate and hydrochloric acid aim.

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

A conical flask contains the marble chips hydrochloric acid and the water that will make the reaction. How can the rate of the reaction between calcium carbonate and dilute hydrochloric acid be measured. 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.

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. A tube to connect the conical flask to the measuring cylinder. 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.
