Ok... I took Chem classes, but that was quite a while ago. I need some help understanding this statement....
"20% aqueous sodium hydroxide (NaOH)"
If I have dry crystal NaOH that I purchased from Home Depot, how do I turn that into 20% aqueous sodium hydroxide. And in particular, how do I do this without dissolving my garage or kitchen. Does the % mean by weight? 20 grams of NaOH for every 100 grams of water?
Thank you all in advance.
