Finding Out the Effect of Hydrochloric Acid on Its Reaction Time with Calcium Carbonate

To investigate the effect of hydrochloric acid on the reaction time of calcium carbonate Objective: To understand whether the concentration of hydrochloric acid affects reaction time with calcium carbonate Assumption: The reaction I study is calcium carbonate + acidic calcium chloride hydrochloride + Carbon dioxide + water. CaCO 3 (S) + 2 HCl (aqueous solution) CaCl 2 (AQ) + CO 2 (g) + H 2 O Increasing the concentration of hydrochloric acid is expected to result in a faster increase in the rate of reaction with calcium carbonate.

Examine how the acid concentration affects the reaction rate between hydrochloric acid and calcium carbonate (magnesium band). We change only one of the variables to make the experiment fair. It is the concentration of acid. In all the experiments we had to maintain the amount of acid, the quality and size of the marble chip, and the temperature of the acid to ensure a fair test.

Influence of concentration on the reaction rate of magnesium and hydrochloric acid Scheme 1: The purpose of this study was to find the effect of acid concentration on the reaction between dilute hydrochloric acid and magnesium. Chemical reaction rate is a measure of the rate at which a reaction occurs. High concentration hydrochloric acid means rapid reaction, low concentration hydrochloric acid means slow and long reaction. - How concentration influences the reaction rate of magnesium and hydrochloric acid. Secondary resources: Chemical reactions only occur if particles have sufficient energy to collide and react This is called collision theory. The minimum energy required to cause this reaction is called activation energy. There are four main factors that influence reaction speed

In this survey, we are investigating the reaction rate. Investigate the reaction rate between calcium carbonate and hydrochloric acid and investigate factors affecting the reaction rate. The reaction rate is the time at which the chemical reaction takes place. A reaction is instantaneous, as explosive explosive (KNO 3) is as slow as other reactions like iron oxidation (rust). The reaction rate is related to "collision theory", and the reaction speed is slow, the possibility of collision is low, indicating that the collision is very high when the reaction speed is fast.
