Quick question about Earthwalker's tek

[bluecereal]

Recently, I performed EarthWalkers Tek on roughly 100g of ACRB. I am currently freeze-precipitating my pulls (super exciting!)

Anyway, I was skeptical of one of EW's measurements; namely this one:

Step 1 / B
Ok if you have done step 1 / A there is no need to add the 500 ml of water mentioned in this step , so go straight to adding the acid !!

If you don't wish to do the freeze thaw start from here .....

Measure out 100g of powdered ACRB , place this in a 2 litre bottle ( preferably ) with a thin neck then add 500ml water then add you're preferred acid to the mix until you have a ph of 2-3 do this with ( white vinegar , hydrochloric acid , citric acid ) " I prefer hydrochloric acid " a cap full usually gets a ph 2.6 ! With vinegar add approx 50-60ml and allow this to sit in heat bath for 1- 1/2
hours gently mixing occasionally !!

I find it hard to believe that 50ml of vinegar would bring the ph of 500ml of water down to 2-3. Does he mean pure vinegar (is that a thing?), or does white vinegar just refer to the regular "diluted to 5%" vinegar. Are these measurements accurate, and could somebody show me the math? Thanks in advance!

PS: I roughly doubled the amount of vinegar during my extraction, which probably wasn't a good idea...

if him and others are getting results then i guess its right, but if your not sure just add white distilled vinegar until you get a ph of 2-3, best to invest in a ph meter or ph papers if your not sure

I couldn't find any local stores selling high range ph papers, so I went without. You're right, I should have just gone with the tek. Should be fine anyway :d

Sorry I couldn't get on earlier to answer you're question but 50ml of normal 5% white vinegar ( table vinegar ) is fine !! Beleive me when I say if you think 50ml isn't sufficient use 60-65 ml you really shouldn't just double measurement !

Although you have doubled the vinegar just add an extra 10-15g lye to help balance it up abit ! Truely buy a ph meter of eBay there anywhere from $8 to $15 and although they seem cheap there very accurate just calibrate it often and look after it and wash it well and it'll last forever !! Goodluck :thumb_up:
