Q21 Tek - Vinegar not turning bark red?

[Swarupa]

I'm currently doing Q21's tek & the vinegar is not turning the MHRB red? I obviously don't want to proceed any further until i know for sure its done the job

Im using white vinegar/solution of aectic acid but it doesnt have any % on there.... could it be too weak?

I also used it pure in the tek 300ml vinegar : 150g MHRB, it smells like a vinegar MHRB mix, but its not anywhere near red, it's chocolate brown.

Really appreciate some help on this asap as i was hoping to add the lime soon...

Thanks in advance

I do not think it is safe to assume bark color as a good indicator of pH. If unsure use a pH paper or do a mini, small quantity extraction.

I have some Litmus Blue papers & they turn red/brown just above the dipped in tip, so it would indicate it is acidic...im just not sure ifits acidic enough

Thanks for getting back to me, you reminded me i have litmus blue papers

I just noticed that where i dip the blue paper in, the solution turns red :?:

Litmus paper becoming red indicates a pH below 4.5, which I think is enough for a good extraction.

Cool thanks man, i just took a shower & the mix settled, the MHRB fiber dropped to the bottom its left an oily red watery solution, so its looking good

You've helped me quite a bit sir, thankyou
