Marble and Hydrochloric Acid Investigation Aim: The aim in this investigation is to see how the concentration of hydrochloric acid, effects the rate in which marble dissolves. Theory (back ground info): There are four ways in which you can speed up the rate of reaction: 1) Using a catalyst 2) Increasing the temperature 3) Increasing surface area of a solid substance 4) Increasing the concentration of a liquid 1) A catalyst is a substance that increases the rate of reaction with out getting used up, for example getting an A4 piece of paper and ripping it up will take to long but if you get scissors it would be a lot quicker, also the scissors do not get used up they can be used again for next time. 2) Increasing the temperature of a substance increases the amount of kinetic energy the particles have. This then allows reacting particles to collide at a faster...
