Find molarity in 1.0 grams of potassium fluoride is dissolved to make 0.10 L of solution.

We are given –

__________________________________________

Using formula –

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

it's 3.2 on edge, i just took the test.
