Excess lithium hydroxide is added to solution and this will lead to crystallization of lithium sulfate which is separated from the solution using filtration techniques.
The reaction that occurred between the sulfuric acid and lithium hydroxide is known as a neutralisation reaction.
The products of this reaction is a salt called lithium sulfate and water.
Upon the addition of excess base (lithium hydroxide) the solution becomes super saturated leading to crystallization of salt from the solution.
The mixture is then filtered using a filtration funnel through gravity filtration process.
The hydrated lithium sulfate is then collected as the residue and dried.
Therefore, excess lithium hydroxide is added to solution and this will lead to crystallization of lithium sulfate which is separated from the solution using filtration techniques.
