How much water is in muriatic acid?
Muriatic acid is considered concentrated Hydrochloric acid. At STP the maximum soluble concenration is about 37.5% HCl. You will usually titrate it to 36% HCl and as low as 34% HCl. Concentrated muriatic acid is always evaporating HCl gas and the concentration is always dropping. For most purposes like "pool cleaning" they cut it to 17% HCl and still call it muriatic acid. Muriatic should have 65% water by weight on average for the concentrated stuff and 83% water by weight for the weaker stuff.
