Investigating How Varying the Concentration of Hydrochloric Acid Affects the Decomposition of Marble Chips

Examining how changes in hydrochloric acid concentration affect decomposition of marble chips We aimed to investigate how changes in the concentration of hydrochloric acid (HCl) affect the breakdown of marble chips (calcium carbonate). The equation for this reaction is as follows. [IMAGE] CaCO 3 + 2 HCl CaCl 2 + H 2 O + CO 2 Background knowledge (What we found through the Internet and Eileen Ramsden's 'Key Science Chemistry') limestone.

In this survey we use CaCO 3 in the form of marble chips and react these chips with hydrochloric acid. The equation for this is as follows. PURPOSE: We are investigating whether the temperature affects the reaction rate of the experiment. The experiment I am doing is how temperature influences the release rate of gas when hydrochloric acid is added to calcium carbonate in the form of a marble chip. 2HCL (aq) + CaCO 3 (s)? H 2 O (I) + CO 2 (g) + CaCl 2 (aq) Preliminary experiment program, evaluation and prediction

Examine how acid concentration affects the reaction rate of hydrochloric acid and calcium carbonate (magnesium band) --- My goal is how acid concentration changes influence the reaction rate of CaCO 3 and HCl It is to investigate. 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.

Study on the influence of different concentrations on the reaction of hydrochloric acid and magnesium The purpose of this study was to investigate how the dilution of water (H 2 0) after dilution of hydrochloric acid (HCL) and magnesium (Mg) affects the reaction rate was. The reaction rate will be measured by the amount of released hydrogen (H 2). It is measured every 10 seconds during the experiment. - Influence of temperature on the reaction rate of magnesium and hydrochloric acid It is investigated how temperature influences the reaction of magnesium and hydrochloric acid and it examines whether reaction accelerates or decelerates as temperature rises. Temperature range from room temperature to 70 degrees

Objective To study the influence of various concentrations on the reaction between magnesium and hydrochloric acid. Understand how the reaction between magnesium and hydrochloric acid occurs when the concentration of hydrochloric acid changes. Introduction In the experiment, magnesium reacted with hydrochloric acid to produce magnesium chloride and hydrogen. - Study on the effect of magnesium metal and dilute hydrochloric acid concentration Objective: To study the influence of concentration on the reaction between dilute hydrochloric acid and magnesium metal. Scientific knowledge: concentrated acid contains many acidic particles
