Rate of Reaction Between Calcium Carbonate and

between experiments as the acid is neutralised by the Calcium Carbonate. · Acid Strength - this is what I am trying to test in the experiment to find out how the strength of the acid affects the rate of reaction. For each experiment, I will be using a different strength of acid.

What determines the strength of an ionic bond? The

2013-10-2 · The fact that calcium carbonate decomposes while sodium carbonate do not is due to the lower charge density of sodium ion. Charge density is proportional to charge/ionic radius (q/r). Both Calcium and Sodium have relatively similar ionic radius but Calcium has a greater charge, which results in Calcium ion having a greater charge density.
