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.

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 stand to hold up the measuring cylinder. 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. Marble chips are mostly made up of calcium carbonate which is a alkaline compound.

Calcium chloride solution is also formed. Using a measuring cylinder add 50 cm 3 of dilute hydrochloric acid to a conical flask. Being alkaline it reacts with hydrochloric acid to produce calcium chloride water and carbon dioxide. With the equation caco3 2hcl cacl2 h2o co2 hypotheses a reaction occurs when particles collide.

Label this line a. 2hcl aq caco 3 s cacl 2 aq co 2 g h 2 o l. This process is based on random particle movement. 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.

Add 0 4 g of calcium carbonate to the flask. A tube to connect the conical flask to the measuring cylinder. The rate of this reaction can be changed by changing the size of the marble chips. Marble chips react with dilute hydrochloric acid to produce carbon dioxide gas.

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. How can the rate of the reaction between calcium carbonate and dilute hydrochloric acid be measured. Immediately connect the gas syringe and start a stop clock. 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 conical flask contains the marble chips hydrochloric acid and the water that will make the reaction. Hcl calcium carbonate calcium chloride carbon dioxide water. The variables that i shall be changing will be the concentration of hydrochloric acid and water. Investigating the rate of reaction between marble chips calcium carbonate and hydrochloric acid aim.
