The question is incomplete, the complete question is;

A pool owner adds a compound containing chlorine to the pool to disinfect it. However, too much of the compound is added. As a result, the water becomes too acidic. What could the pool owner do to reduce the acidity of the pool?

He could add another acid to the pool to compete with the existing acid.

He could add a metal salt to the pool to precipitate the acid.

He could add a base to the pool to neutralize the acid.

He could add a base to the pool to neutralize the acid.

Explanation:

The reaction between an acid and a base is called a neutralization reaction. A neutralization reaction is defined as a reaction between an acid and a base leading to the formation of salt and water only.

If the owner of the pool discovers that the pool has become too acidic, all that needs to be done is to introduce a base into the pool that will neutralize the acid according to the reaction;

Acid + base > salt + water

the tides are influenced by both the moon and the sun, it's easy to see that when the sun lines up with the moon and the earth, as during a new moon or full moon, the tidal effect is increased. these are known as spring tides, named not for the season, but for the fact that the water "springs" higher than normal. on the other hand, if the sun and the moon are 90 degrees apart in relation to an observer on earth as during the first quarter moon or third quarter moon, then high tides are not as high as they normally would be. this is because despite its greater distance, the sun's mass allows it to exert enough gravitational force on the oceans that it can negate some of the effects of the moon's pull. this phenomenon of lower high tides is called a neap tide. if you need more information on this topic visit moonconnection.com.

im not exactly sure but i think its b!
