An experiment to find out how changing the concentration of acid

Experiment to understand how the change in acid concentration affects reaction rate. Plan objective: I want to know how changing the concentration of hydrochloric acid (HCL) affects the reaction rate. Hydrochloric acid reacts with marble chips (small, medium, large). In my experiment, I change the variable. This is the concentration of acid. Use HCL concentrations from 0.5 mol / dm 3 to 0 mol / dm 3. I use 3 grams of marble chips for each chip size.

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.

Study of the reaction rate of sodium thiosulfate and hydrochloric acid Objective: Four experiments were conducted to investigate how the reaction rate changes with different concentrations of sodium thiosulfate, hydrochloric acid and water. As an inert stable liquid, change the concentration of sodium thiosulfate without changing the final amount of solution using water. All atoms in water molecules have complete shells, so they do not react with other chemicals. Fixtures: beaker, measuring cylinder and black paper tube optical probe and blue box data fixing lamp in total 30 cm 3 H 0, 50 cm 3 Na 2 SO 3, 12 cm 3 HCl Method: We changed the concentration of sodium thiosulfate and hydrochloric acid Wish, but please do not change the total Quantity For this purpose, mix sodium thiosulfate and water at different ratios and always include a certain amount of acid.
