What is the pH of a substance with a hydrogen concentration of 1.0 x 10-13?
Nikolay [14]

Answer:

Favorite Answer

1.0 x10^-14 = (1.0 x 10^-13) (x)

x = 1.0 x 10^-1 = 0.1 M (this is the [OH-])

pOH = -log 0.1 = 1.0

Explanation:

I hope this helps :) sorry if not :(

Which would have a higher pH, a 0.1 M solution of a strong acid, or a weak acid? Why?
DerKrebs [107]

Answer:

0.1 M weak acid

Explanation:

The term pH simply means power of hydrogen which is basically a log (the exponent to base 10 of the concentration) of the concentration of the hydrogen ions.

Weak acids have a higher pH since their hydrogen concentration is lower than that of strong acids.

What is the ph of a solution of 1.0 × 10-9 m naoh (include 1 digit after the decimal in your answer)?
Eduardwww [97]

Answer:

pH=5

Explanation:

Hello,

In this case, for the dissociation of the sodium hydroxide into sodium and hydroxyl ions we have:

NaOH\rightarrow Na^++OH^-

Which is a 100% dissociation as sodium hydroxide is a strong base, therefore, the concentration of the hydroxyl ions are 1.0x10⁻⁹. For that reason, the pOH could be computed as:

pOH=-log([OH^-})=-log(1.0x10^{-9})=9

Finally, from the definition of pH, we have:

pH+pOH=14\\pH=14-pOH=14-9\\pH=5

Best regards.
