Preparing Percentage Solutions.
(Anthonys Annual.)
By C. C. Sherrard, Ph.D.
The first table gives percentage solutions ; the second gives parts in i,ooo or less. The use of the first is as follows: Run down column one until the correct percentage wanted is found, then move to the right along the line until the column is found giving the amount of fluid measure to be made up ; at the inter-section will be found the weight of salt required. It must be remembered that this is the amount of water to take, and not q.s. water to make the volume; also that these tables are true only for water, and not for alcohol or other fluids.
For Making any Quantity of Percentage Solutions.
