Don't mix dilution and ratio...

Ratio means you have x parts of A and y parts of B.

x : y

Dilution refers to the total volume.

x : (x+y)



well iguess i can buy that cause tat is the theory i have been supporting till date... so a dilution can never be represented in ratios!!! hope moljul is clear about my problem and its importance too :D



You only have to mention it properly...

When you dilute something 1:4 it is a ratio of 1:3. B)

B)

so true!!!! :D

and a 1:2 dilution is a 1:1 ratio!!!

What makes U express dilution in ratio?

-Doki-

Words count. If you say "solution A was diluted 1:2 in solution B", it means "1 part of solution A in a total volume of 2 parts". If you say "solution A and solution B were combined in a 1:1 ratio", it means "1 part of solution A was mixed with 1 part of solution B", which, in this case, results in the same final solution.

This equivalency is not always the case, however. If you say "solution A was diluted 1:4 in solution B", this is not the same as saying "solution A and solution B were combined in a 1:4 ratio", because in the former case you have 1 part of A for every 3 parts of B in a 4 parts final volume, whereas in the latter case, you have 1 part of A for every 4 parts of B in a 5 parts final volume.
