PH of solution that has H3O equals 2.1 x 10 to the -8?

Answer 1

1.15 (apex i gotchu)

Answer 2

The pH of a solution with a hydronium ion concentration of 2.1 x 10^-8 M is 7.68. This can be calculated by taking the negative logarithm (base 10) of the hydronium ion concentration. The formula for pH is pH = -log[H3O+].

Answer 3

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

Answer 4

pH = -log[H3O+] ----> pH = -log(2.1x10^-8) ----> pH = 7.68

Answer 5

What is the hydronium ion concentration of an aqueous solution with a pH = 2.00?

Answer 6

pH = 2.00

Then by inverse function of mathematics.

[H^+] = 10^(-pH)

Henc subctituting

[H^+] = 10^(-2) =

[H^+] = 0.01

Answer 7

Really Acidic e.g Sulphuric Acid

Answer 8

Very acidic.

Answer 9

1 x 10^-2 m

Answer 10

1.70
