Response to The ambigity of "dilution 1:3"

In dilution, there are THRREE volumes, A the orginal concentrate, B the volume of solvent, C the final volume

In dilute 1:3 only TWO volumes are specified, 1, and 3 one of these two must be the original stock, not necessary 1

Dilute 1:3, UNSPECIFIED, has three possible meanings

1 part stock add solvent to make 3 part final 1 part of stock + 3 part of water

1 part of water + 3 part of stock
