Explanation:
To minimize the sharp pH shift that occurs when a strong acid is added to a solution, IT IS PRACTICAL TO ADD A WEAK BASE.
When a strong acid is added to a solution, it usually brings about a sharp change in the pH of the concerned solution. To avoid this, one can add a weak base to the solution first. The weak base will serves as a buffer for the strong acid and prevents the solution from experiencing sharp pH variations.
Answer:
The percentage composition of a given compound is defined as <u>the ratio of the amount of each element to the total amount of individual elements present in the compound multiplied by 100. </u>Here, the quantity is measured in terms of grams of the elements present.

Catalyst, in chemistry, a substance that speeds up a reaction without itself being consumed. Enzymes are natural catalysts responsible for many important biochemical reactions.
Most solid catalysts are oxides, sulfides, halides of metals or metallic elements, and metalloid elements boron, aluminum and silicon. Gas and liquid catalysts are usually used in pure form or in combination with suitable carriers or solvents. Solid catalysts are usually dispersed in another material known as a catalyst support.
