Try in the freshly prepared deionized water, if your solvent is water

Mouna Khiari

no i can't because Zinc acetate is not soluble in deionized water but it is soluble in alcohol. then my solvent is alcohol.

Use zinc nitrate. or dissolve acetate in hot water.

I work with thin films and I make the deposit thin films by sol-gel. I have to prepare a viscus solution. I can't use water.
