Marble Chips And Hydrochloric Acid
Describe how you could investigate.
Marble chips and hydrochloric acid. Pour the acid into the conical flask and add the marble chips 5. Figure 9 shows the apparatus the student used. 9 marble chips are mainly calcium carbonate caco3. Marble chips react with dilute hydrochloric acid to produce carbon dioxide gas.
These are reactions that transfer energy to the surroundings. Place 40cm 3 of hydrochloric acid in an conical flask add 20g of marble chips place a loose plug of cotton wool in the neck of the flask to prevent acid spray escaping place the whole apparatus on a balance and find its mass. Being alkaline it reacts with hydrochloric acid to produce calcium chloride water and carbon dioxide. We will be investigating what changes the rate of reaction.
I am investigating how the rate of reaction between marble chips and hydrochloric acid is altered when the concentration is changed. 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. Image carbonate acid chloride dioxide. Caco3 2hcl h2o co2 this is the reaction we will be investigating.
This is the word equation for my investigation calcium hydrochloric calcium carbon water. You then fill a bowl with water along with a boiling tube and straight after attach the delivery tube at the end of the boiling tube 4. 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. 9 1 complete and balance the equation for the reaction between marble chips and hydrochloric acid.
This process is based on random particle movement. This reaction between marble chips calcium carbonate and hydrochloric acid is an exothermic reaction. Investigating the rate of reaction between marble chips calcium carbonate and hydrochloric acid aim. Marble chips are mostly made up of calcium carbonate which is a alkaline compound.
Secondly weight out 3 grams of marble chips for each concentration 3. First you measure out 25cm3 of hydrochloric acid 2. With the equation caco3 2hcl cacl2 h2o co2 hypotheses a reaction occurs when particles collide. The temperature increase can be detected using a thermometer.
A student investigated the rate of reaction between marble chips and hydrochloric acid hcl.
