making CDH

Hello all

I'm really mathematically challenged so apologies in advance for this question.

I was stumped on the Citric Acid part of making CDH. I have a bottle of citric acid solution which has no water added as yet. It contains 60gm of Citric Acid. As this makes up a 50% solution, do I simply use only 21gm of the CA crystals as this would make it 35% of the 60gm and top up the 125ml bottle with distilled H2O?

Thank you

I gave you these instructions before and here they are again:

Hi ShelfRespect,

Do this. Add the water to your citric acid powder so that you end up with 125 ml of 50% citric acid. Then add an additional 55 ml to that. What you'll end up with is 180 ml of 35% citric acid. Here's the calculator that I used to figure that:

easycalculation.com/chemistry/dilution-of-solutions.php

Volume Before Dilution (V1): .125 L
Concentration Before Dilution (M1): 50% Mol/L
Concentration After Dilution (M2): 35% Mol/L
Volume After Dilution (V2): 0.1785 L
Volume Of Solvent Added During Dilution (V): 0.05357 L (I bumped this up to 55 ml)

Then just follow all the directions. I would recommend that you change to hcl when you can because it tastes so much better.

Hope this helps,
Scott
