Answer:
            A Basic solution with a ph of 9.82 has a hydroxide concentration of 6.60 × 10⁻⁵ M.

Explanation:
                   As we know,
When,
                  pH = 7 (The Solution is Neutral)

                  pH < 7 (The Solution is Acidic)

                  pH > 7 (The Solution is Basic)

So, as given pH 9.82 is greater than 7, Hence, it is basic.
As we known,

                 pH + pOH  = 14

                 pOH  = 14 - 9.82

                 pOH  =  4.18

Concentration is calculated by taking Antilog,

                [OH⁻]  =  10^-pOH

                [OH⁻]  =  10^-4.18

                [OH⁻]  =  6.60 × 10⁻⁵

A  basic  solution with  PH of 9.82  has  a  hydroxide  concentration  of  1.51  x10^-10 M

The  solution  is  basic  since   the   PH  is  greater  than    7  while  the  concentration  is  calculated  as follows

Ph  =  -log  (h+)
therefore  -log(H+)  =  9.82

H+ =10^-  9.82=  1.51  x10^-10
