Reading about Pyro, I am confused when directions are given to make a "standard working solution". When I read "To make a standard working solution mix 1 part A with 1 part B with 100 parts water", does that mean, & this is an example: 1ml part A, 1 ml part B, 100 ml water? So to make a working solution of 1000ml what would be the amounts needed for part A & part B & water?
Thanks for you input.

Re: Making a standard working solution
Are you really asking that question ? By how much do you multiply 100 ml to have 1000 ml ? So you multiply A & B by the same amount.

The simplest way to do this is to add a zero to each solution. Thus, 1:1:100 would become 10:10:1,000. This is the easy way, and yes you will come up with 1,020ml. . . this is plenty close enough. What is more important is to make sure you always mix exactly the same. Write it down; refer to your notes every time you mix chemistry. Consistency is absolutely the most important thing to keep in mind. Just to be clear; if you need a 2:2:100 mix, add a zero and you get 20:20:1,000. It is simply a ratio of the two parts of stock chemistry to water. Hope this helps.
