Hi
I am trying to Masterbatch, dual lye and Vinegar.
Can someone please check if the vinegar neutralising bit is right?
My recipe has 95% NaOH and 5% KOH
NaOH= 128 g
KOH = 7.5g
Total water = 316g
I have masterbatched the lye already so I want to add 50% water.
316 - 128 - 7.5 = 180g vinegar instead of water
28 g of vinegar neutralises 1 g NaOH
95% of 180g = 171 g NaOH/28 = 6 g NaOH extra
28 g of vinegar neutralises 1.4 g KOH
5% of 180 g = 9 g KOH/28 = 0.32 x 1.4g = 0.45 extra.
Is that right?
How in heavens name do I weigh 0.45g KOH?
Anyone know how much an 1/8 of KOH weighs?
