Marble chips and hydrochloric acid experiment equation.
3m hydrochloric acid with large marble chips 1 5m hydrochloric acid with small marble chips 3m hydrochloric acid with small marble chips a reading was taken initially every 15 seconds for a minute and then every 30 seconds for the next 4 minutes.
Hydrochloric acid to react with the marble chips independent variable marble chips to react with the acid dependent variable stopwatch to accurately time the experiment spatula to handle the marble chips measuring cylinder to precisely measure out different concentrations of hydryochloric acid electric balance to measure the mass g of the marble chips bung.
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 are mostly made up of calcium carbonate which is a alkaline compound.
This was done as the first trial showed that in the first 2 minutes the.
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.
How can the rate of the reaction between calcium carbonate and dilute hydrochloric acid be measured.
Using the apparatus shown the change in mass of carbon dioxide can be measure with time.
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.
Hcl calcium carbonate calcium chloride carbon dioxide water.
The rate of this reaction can be measured by looking at the rate at which the product carbon dioxide gas is formed.
An investigation of the reaction between marble chips and hydrochloric acid.
Marble chips placed onto pieces of paper.
This process is based on random particle movement.
Marble chips calcium carbonate caco 3 react with hydrochloric acid hcl to produce carbon dioxide gas.
Calcium chloride solution is also formed.
