Answer:
The solution is warm or heated to insure that all the antacid reacts.
Explanation:
The purpose of warming the solution is vital as it gives way to all the antacid to reacts. Finally, the remaining un reacted acid is titrated with base (NaOH) to determine or to realize the amount left over and hence, the amount that reacted with the tablet. The chemical reaction which occurs is:
NaOH + HCl -------> NaCl + H 2 O
Answer:
Due to its cohesive nature
Explanation:
cohesion is a measure of how well molecules stick to each other or group together. It is caused by the cohesive attractive force between like molecules. Cohesion is an intrinsic property of a molecule, determined by its shape, structure, and electric charge distribution. When cohesive molecules approach each other, the electrical attraction between portions of each molecule holds them together.
