Actually I meant the absolute last question. About the solubility in water. Something like 150g in 100cm^3 water.

I actually misunderstood one question. The question about barium sulfate. The part where you had to describe how to filter it and then wash with distiller water, I wrote something completely different.

hmm, it was precipitation method

I thought you had to write why it reacted. I explained how they ionised in water and everything. Lost three marks there.

YES I CHOSE CORRECTLY !!!!!

And btw, i wrote tht the barium sulphate precipatate was filtered out, then washed, and then dried in a dessicator or with filter paper. So, distilled water was necessar to mention? I just said washed with water.
