Sodium chloride I.E. NaCl is an ionic compound formed by the reaction between sodium and chlorine. it is also known as common salt .
Answer is: Ksp for magnesium hydroxide is 1,1·10⁻¹¹.<span>
Chemical reaction: Mg(OH)</span>₂(s) → Mg²⁺(aq) + 2OH⁻(aq).
s(Mg(OH)₂) = 1,4·10⁻⁴ M.
s(Mg(OH)₂) = s(Mg²⁺).
s(OH⁻) = 2s(Mg(OH)₂).
Ksp = s(Mg²⁺) · (s(OH⁻))².
Ksp = 1,4·10⁻⁴ M · (2,8·10⁻⁴ M)².
Ksp = 1,1·10⁻¹¹.
In addition to protons and neutrons, all atoms have electrons, negatively charged particles that move around in the space surrounding the positively-charged nuclear core. But unlike protons, the number of electrons can and does change without affecting the kind of element an atom is!
