Marble And Hydrochloric Acid Reaction

If the acid fizzes on your sample your rock is probably marble.

Marble and hydrochloric acid reaction.

Caco3 s 2hcl aq 61614. If the acid only makes the rock wet wipe the rock with a paper towel and go back to homogeneous looking rocks. This process is based on random particle movement. Being alkaline it reacts with hydrochloric acid to produce calcium chloride water and carbon dioxide.

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. 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. Wipe all acid off the rock sample with a paper towel.

3 754 words investigating the kinetics of reaction between sodium thiosulphate and dilute hydrochloric acid pages. Answered sep 27 2018 author has 93 answers and 88 9k answer views marble is a thermally metamorphosed limestone. 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. 2hcl caco3 cacl2 h2o co2 gas bubbles.

Caco3 2hcl h2o co2 this is the reaction we will be investigating. With the equation caco3 2hcl cacl2 h2o co2 hypotheses a reaction occurs when particles collide. Marble is calcium carbonate and thus behaves in the same way. 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.

The rate of reaction between sodium thiosulfate and hydrochloric acid pages. How does changing the concentration of hydrochloric acid affect the speed it reacts with marble chips.
