Lithium sulfate

Preparation

I prepared it by reaction of lithium hydroxide and dilute sulfuric acid:

2LiOH + H2SO4 = Li2SO4 + H2O

Growing

As always, I used slow evaporation method to grow the crystals. Growing was complicated by very strong tendency of lithium sulfate solution to creep.

It seems that pH affects crystal morphology: alcaline pH produces very thin plates, while from acidic solutions thicker plates grow.

Safety

Lithium has low acute toxicity, but consumption of it must be avoided.
