< Question 6 of 10
>
At 25 °C, what is the hydroxide ion concentration, [OH-], in an aqueous solution with a hydrogen ion concentration of
[H"]=1.7 x 10-6 M?
[OH-] =

The hydroxide ion concentration, [OH-] : 6.31 x 10⁻⁹ M

pH=- log [H⁺]

pH+pOH= 14

A hydrogen ion concentration of  [H"]=1.7 x 10⁻⁶ M

the answer is na (sodium)

b. accuracy of the data matters alot more than its number of digits, organization or amount of detail. quantitative observation is more accepted than the qualitative observation.
