The basics
Which of these is a solution?
AnswerSalt water
Salt dissolves completely in water, forming a clear, uniform mixture.
Going deeper
What is a saturated solution?
AnswerA solution that holds as much solute as it can at that temperature
Once a solution is saturated, extra solute stays undissolved at that temperature.
What is the pH of pure water at 25°C?
Answer7
Pure water at 25°C has equal hydrogen and hydroxide ions, giving a neutral pH of 7.
For most solid solutes in water, what happens to solubility as the water gets warmer?
AnswerIt usually increases
Warmer water generally dissolves more of most solids, such as sugar.
Expert level
Why does a fizzy drink go flat faster when it is warm?
AnswerGases are less soluble in warmer liquids
Unlike most solids, gases become less soluble as temperature rises, so carbon dioxide escapes.
Molarity measures a solution's concentration as moles of solute per what?
AnswerLitre of solution
Molarity (M) is moles of solute divided by litres of the whole solution.
