a) Supersaturated solution contains more solute than expected.
b) Magnesium sulfate is soluble in water but not hydroxide. Mg2+ will be the answer.
c) Lewis acid-base concept => acceptance and donation of a pair of nonbonding electrons. So, it explains acid-base nature of proton acceptors better than other concepts.
d) Sodium oxide(Na2O) reacts with water to form NaOH (Base). It acts as lewis base in water
e)
So, molarity of NaF will be 2 x 10-5 M for precipitation.
a.) b.) c.) d.) e.) An unstable solution with more than the maximum solute is O...
