Marble Chips And Hydrochloric Acid Equation

The rate of this reaction can be changed by changing the size of the marble chips.

Marble chips and hydrochloric acid equation.

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. Marble chips are mostly made up of calcium carbonate which is a alkaline compound. 2hcl aq caco 3 s cacl 2 aq co 2 g h 2 o l.

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. 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.

Label this line a. 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. Immediately connect the gas syringe and start a stop clock. Hcl calcium carbonate calcium chloride carbon dioxide water.

This process is based on random particle movement. A stand to hold up the measuring cylinder. Using a measuring cylinder add 50 cm 3 of dilute hydrochloric acid to a conical flask. The variables that i shall be changing will be the concentration of hydrochloric acid and water.

A tube to connect the conical flask to the measuring cylinder. 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. How can the rate of the reaction between calcium carbonate and dilute hydrochloric acid be measured. Investigating the rate of reaction between marble chips calcium carbonate and hydrochloric acid aim.

Add 0 4 g of calcium carbonate to the flask. Marble chips calcium carbonate caco 3 react with hydrochloric acid hcl to produce carbon dioxide gas. An investigation of the reaction between marble chips and hydrochloric acid. 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.
