To keep the kead nitrate in solution: otherwise it might precipitate lead.

Its Acidic... HydroBromic Acid is acidic, even if you dilute it with water.

a dilute aqueous solution of KMnO4 may be used.

A concentrated acid has more acid than water and a dilute acid has more water than acid. True facts, otherwise known as its molarity. The greater the molarity the more concentrated it is (moles of acid/ liter of solution)

A dilute solution is a solution in which there is a small amount of solute (the thing that gets dissolved) compared to the total amount of possible solute that can be dissolved in the solvent (the thing that does the dissolving). A concentrated solution is when there is a lot or all solute that can possibly fit in the solvent.
Dilute sulphuric acid is an aqueous solution, formed by adding water to sulphuric acid, resulting in a homogeneous mixture.
to prepare 1N we have to dilute 40gms of NaOH in 1 litre of water as for NaOH normality =molarity so to prepare 0.1N NaOH we have to dilute 4gms of NaOH in 1 litre of water..
