Hello everybody:
I really would like to ask you a question and want to have your answer about it..

I do have a ferric sulphate solution and i want to dilute it ; how can i do that if

1-   my ferric sulphate is 75 % concentration and i want to dilute 20 times in a tank of 20 Litre ?
2- my ferric sulphate is 35 % concentration and i want to dilute 10 times in 20 litre tank ?

3- if i do not know the concentration of the original solution and i want to dilute it 30 times in a tank of 20 litre ?

Please try to help with answering this question in three cases. and try to support your answers with numbers..

Looking forward to hear from you

Regards

Sorry, I'm not sure what you're trying to ask - quantities? protocols?

The relationship equation would be:
(Final volume/dilution factor)= Volume taken from original concentration

Example for (1): Dilution factor=20 times

(20Litre/20)= 1Litre

*so you need to take 1Litre of Ferric Sulphate(75%) and dilute it with water until 20 Litre
