Answer: a. acid

Explanation:

a. Acids are those substances which either donates hydrogen ions (H^+) when dissolved in water or accepts a pair of electrons.

HCl\rightarrow H^++Cl^-

b. Buffer is a solution which resist changes in pH on addition of small amounts of acid or base into it.

c. Bases are those substances which either donates hydroxide ions (OH^-) when dissolved in water or donates a pair of electrons.

NaOH\rightarrow Na^++OH^-

d. Indicators are chemical compounds which show a change or appearance in color at particular pH. Example: litmus

15% =  15 grams of solute in 100 mL solution

15 g --------------- 100 mL
?? ------------------ 1000 mL

1000 x 15 / 100 = 

15000 / 100 => 150 g of solute

PLEASE<br> What is the H30+ concentration of a solution with a pH of 3?
Alenkinab [10]
PH = -log[H3O+]
Solving for [H3O+] gives
[H3O+] = 10^-pH
             = 10^-3 
or 1x10^-3 M
