Michael analyzes a chemical and determines it is calcium chloride (cacl). after further tests, michael declares that calcium chloride is a salt and has no effect on ph.

a. this means that the chemical will release:

(a) only h= ions into water.

(b) only oh - ions into water.

(c) equal amounts of oh- and h+ ions into water.

(d) neither oh- or h+ ions into water.

b. when placed in water, wha ions does this chemical release?

A)

Solution:

Salt is formed when an acid reacts with a base. We call this reaction as a Neutralization reaction.

For example  

is formed from a strong base and  strong acid HCl as shown in the Equation

is a salt which produces ions and ions into water

So the Answer is option D

Neither or ions into water.

B)

Solution:

Arrhenius Theory: An acid is a substance which produces one or more hydrogen ions, (H+) in aqueous solution.

Examples:

A Base is a substance which produces one or more hydroxyl ion or hydroxide ion (OH-) in aqueous solution.

Examples

Please note: (aq) stands for aqueous which means in the presence of water that is, water acts as a solvent.

is formed from a strong base and  strong acid HCl as shown in the Equation  

So when placed in water as it is formed from a strong base it releases OH- ions and as it is formed from a strong acid it releases H+ ions .

So, option C is the Answer

Equal amounts of OH- and H+ ions into water

i think that the answer is c
