Question

If the hydrogen ion concentration [H*] is 1.00 x 10-10 the solution isacidic basic (alkaline)neutral or none of the above

Answer 1

basic (alkaline)

Step-by-step explanation

To know if the solution is acidic, basic or neutral, you need to determine the pH of the solution.

`pH=-log[OH^+]`

Putting [OH⁺] = 1.00 x 10⁻¹⁰ into the pH formula, we have

`\begin{gathered} pH=-log(1.00*10^(-10)) \\ \\ pH=-(-10) \\ \\ pH=10 \end{gathered}`

Note that the pH scale ranges from 0 to 14, with 7 being neutral. pHs less than 7 are acidic while pHs greater than 7 are alkaline (basic).

Therefore, the solution is basic (alkaline)
