Respuesta :
The NaOH Concentration is [tex]2.8\times10^{-3}[/tex] M.
What is concentration?
Concentration is calculated by dividing a constituent's abundance by the mixture's total volume. Mass concentration, molar concentration, number concentration, and volume concentration are four different categories of mathematical description. Any type of chemical mixture can be referred to by the term "concentration," however solutes and solvents in solutions are most usually mentioned. There are different types of molar (quantity) concentration, including normal concentration and osmotic concentration.
What is ksp?
ksp stands for the solubility product constant. When a chemical substance in the solid form is in chemical equilibrium with a solution of that molecule, a solubility equilibrium is a sort of dynamic equilibrium that develops. The solid may dissolve chemically by reacting with another component of the solution, such as acid or alkali, or dissolving unaltered.
[tex]k_{sp} = [(A^{+})^{a} (B^{-})^{b} ][/tex]
[tex]k_{sp}=[/tex] solubility product constant
[tex]A^{+}[/tex] = cation in an aquious solution
[tex]B^{-}[/tex] = anion in an aqueous solution
a, b = relative concentrations of a and b
[tex]Ca[OH]^{2} \rightleftharpoons Ca^{2} +2OH^{-}[/tex]
[tex]k_{sp} = [(Ca^{2+}) (OH)^{2-} ][/tex]
=[tex]1 \times [OH^{-} ]^{2} =8\times10^{-6}[/tex]
[tex][NaOH] = [OH^{-} ]=8\times(10^{-6})^{1/2}[/tex]
=[tex]2.8\times10^{-3}[/tex]
