Calculate the amount of sodium hydroxide, NaOH, in 25.0 cm 3 of solution of concentration 0.1 mol/dm 3. If the amount in mol of a solute in a given volume of solution is known, its mass can also be ...

Sodium hydroxide is added to a cylinder of aluminum nitrate, precipitating out aluminum hydroxide. When additional base is added, the precipitate dissolves. The reactions can then be reversed with the ...

Sodium oxide and potassium oxide dissolve in water to produce alkalis: • Na 2 O(s) + H 2 O (l) → 2 NaOH (aq) • K 2 O(s) + H 2 O (l) → 2 KOH (aq) • 2K(s) + 2H 2 O (l) → 2KOH (aq) + H 2 (g) + heat ...
