0.5 mol of sodium hydroxide is dissolved in 2 dm 3 of water. Calculate the concentration of the sodium hydroxide solution formed. \(Concentration~in~mol/dm^{3} = \frac{amount~of~solute~in~mol}{ ...

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 ...
