Marble And Hydrochloric Acid Reaction

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

Marble and hydrochloric acid reaction.

The rate of reaction between sodium thiosulfate and hydrochloric acid pages. Caco3 s 2hcl aq 61614. Marble is calcium carbonate and thus behaves in the same way. If the acid fizzes on your sample your rock is probably marble.

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. Powdered marble reacts with hydrochloric acid to release bubbles of carbon dioxide gas. With the equation caco3 2hcl cacl2 h2o co2 hypotheses a reaction occurs when particles collide.

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. 3 754 words investigating the kinetics of reaction between sodium thiosulphate and dilute hydrochloric acid pages. 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. 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.

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. Marble chips are mostly made up of calcium carbonate which is a alkaline compound. This process is based on random particle movement. 2hcl caco3 cacl2 h2o co2 gas bubbles.

How does changing the concentration of hydrochloric acid affect the speed it reacts with marble chips. Being alkaline it reacts with hydrochloric acid to produce calcium chloride water and carbon dioxide.
