Any substance with a pH less than 7 is considered to be acidic.
A solution with pH of 2 has a hydrogen ion concentration of 1.0 x 10-2 mols/L
pH = -log[H3O+] ----> pH = -log(2.1x10^-8) ----> pH = 7.68
What is the hydronium ion concentration of an aqueous solution with a pH = 2.00?
pH = 2.00
Then by inverse function of mathematics.
[H^+] = 10^(-pH)
Henc subctituting
[H^+] = 10^(-2) =
[H^+] = 0.01
Really Acidic e.g Sulphuric Acid
Very acidic.

3 and 7 multiplies to 21 and equals to 10
21 is the only solution of that equation.
The statement 10 plus 21 equals 31 in total. It can also be written as 10 + 21 = 31.
21 + 10 = 31
The solution is k = 9.
9+10=21 because if you add 9+10 to 1+1, it equals 21

9 times 7/3 = 21
14.4762
10 + 11 = 21
No you can not prove that 9 +10 = 21.
