Question

if the industrial solution
solution of hydrochloric acid 10% by mass having density 1.30 g/cc. Calculate the normality of this solution​

Answer 1

Answer:

By the way, 37% is commercial concentrated hydrochloric acid? In this case, the accuracy of indicating the concentration is not very high. Moreover, it changes with every operation (vessel opening, pouring, storage, etc.). This should be checked - best of all in a diluted solution - in this case, the concentration does not "creep" so quickly. Usually, a calculated solution is made, and then the exact concentration of hydrochloric acid is determined (this is for analysts). In addition, if there is a container with some kind of inscription on the shelf, you should not treat it with absolute truth (especially for impurities) - it is not known who and what did with it before you ...
