What is meant by 37% HCl?
% refers to solution concentration in percentage and “(w/w)” refers to solute and solution amount given in grams (i.e., percentage by weight). This means a 37% (w/w) Hydrochloric acid contains 37 g of HCl per 100 g of solution. This means the weight of the 1 ml of hydrochloric acid solution is 1.2 g at 25°C.
