The theory is said that increasing the concentration can increase the rate of reaction by increasing the rate of molecular collisions. It takes longer for this balloon to inflate to the same extent as the first balloon because the reaction slows down considerably as the concentration of HCl and the surface area of the Mg approach zero toward the end of this reaction. The solubility of sodium chloride does not change much with temperature, so simply cooling the solution is unlikely to form crystals. Sodium Thiosulphate and Hydrochloric Acid.
