Info on how much concentrated acid or base is required to make up 1 liter of 1M dilute acid or base.
A Table showing the no. of mls, percentage, SG, and Molarity of the acids is given.
Quantities used are approximate and acceptable for practical qualitative analysis.
Reagents tend to be hygroscopic or volatile.
