Powdered marble reacts with hydrochloric acid to release bubbles of carbon dioxide gas.
Marble and hydrochloric acid reaction.
If the acid only makes the rock wet wipe the rock with a paper towel and go back to homogeneous looking rocks.
2403 words10 pages an investigation into how changing one variable influences the rate of reaction between marble chips and dilute hydrochloric acid planning section when dilute hydrochloric acid reacts with marble chips the following reactions occurs.
If it is pure it entirely consists of calcium carbonate caco3 the reaction with hcl gives strong effervescent due to the coming off of co2 gas in the air.
Being alkaline it reacts with hydrochloric acid to produce calcium chloride water and carbon dioxide.
Marble chips are mostly made up of calcium carbonate which is a alkaline compound.
How does changing the concentration of hydrochloric acid affect the speed it reacts with marble chips.

Caco3 2hcl h2o co2 this is the reaction we will be investigating.
If the acid fizzes on your sample your rock is probably marble.
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 to stop the gas from escaping weighing boat to hold the marble chips in when weighing variables.

This process is based on random particle movement.
Cacl2 aq h2o l co2 g in this experiment i am going to see if temperature affects the reaction rate between marble chips and hydrochloric acid by timing the release of carbon dioxide in the reaction.
Marble is calcium carbonate and thus behaves in the same way.
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.
Wipe all acid off the rock sample with a paper towel.
