Marble and hydrochloric acid reaction.

Marble chips are mostly made up of calcium carbonate which is a alkaline compound. 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. The rate of reaction between hydrochloric acid and sodium. If the acid only makes the rock wet wipe the rock with a paper towel and go back to homogeneous looking rocks.

If the acid fizzes on your sample your rock is probably marble. How does changing the concentration of hydrochloric acid affect the speed it reacts with marble chips. Answered sep 27 2018 author has 93 answers and 88 9k answer views marble is a thermally metamorphosed limestone. Marble is calcium carbonate and thus behaves in the same way.

Caco3 2hcl h2o co2 this is the reaction we will be investigating. 2hcl caco3 cacl2 h2o co2 gas bubbles. This process is based on random particle movement. The rate of reaction between sodium thiosulfate and hydrochloric acid pages.

With the equation caco3 2hcl cacl2 h2o co2 hypotheses a reaction occurs when particles collide. Wipe all acid off the rock sample with a paper towel. 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.

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. Powdered marble reacts with hydrochloric acid to release bubbles of carbon dioxide gas.
