Marble Chips Experiment Rates Of Reaction

Prediction when the concentration of acid increases more gas will be given off faster.

Marble chips experiment rates of reaction.

Marble chips and hydrochloric acid rates of reaction 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 reaction rate will be directly proportional to the hcl concentration. In the investigation i am going to find out how the surface area affects the rate of reaction by measuring the amount of gas produced and weight loss in a reaction between small large pieces of marble chips calcium carbonate and hydrochloric acid per minute. As the size of the marble chips is increased then the reaction rate will decrease.

The rate of reaction can be calculated using the following equation. These are reactions that transfer energy to the surroundings. Caco3 2hcl h2o co2 this is the reaction we will be investigating. The rate of reaction increases this reaction between marble chips calcium carbonate and hydrochloric acid is an exothermic reaction.

The units for rate of reaction will usually be grams per min g min an investigation of the reaction between marble chips and hydrochloric acid. The rate of the reaction will decrease as hcl is consumed. 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.
