Chemistry Coursework Lime is a common alkali. Its chemical name is calcium hydroxide. It is a white powder. When lime is added to acid, it gets hot. I am going to investigate how the concentration of acid affects the heat given out. Problem: I am going to investigate how the concentration of hydrochloric acid affects the heat given out when it's reacted with calcium hydroxide. Prediction: I predict that the more concentrated the hydrochloric acid is the more heat will be given out. I predict this because the more hydrochloric acid particles there are compared to the amount of water particles there are, the more collisions that will take place thus giving out more heat. When the concentration of acid is lower there are more water particles which won't give out as much heat when they react with the calcium hydroxide. The product of the experiment will be: calcium chloride and...
