Question 23 of 25 Which of the following best defines a basic solution?
A. A solution with a pH less than 7
B. A solution with a pH greater than 7
O C. A solution with a pH less than 0
O D. A solution with a pH equal to 7
SUBMIT

B.A Solution with a pH greater than 7

A

Explanation:

A "Basic solution" Or a base solution is a solution that has less than a level 7 of pH levels

So the answer would be A

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l
