10% NH4OH, 90% water, w/w. I'd like to know how to make a solution of NaOH that has comparable neutralizing power, without resulting in PH spikes from additional OH that is released.

How to calculate 10% NH4OH eqv solution of NaOH, taking into consideration extra OH? Hi, I'm wanting to make a solution of NaOH that has the same neutralizing power per quantity as 10% w/w NH4OH. Given that a 10% solution of both will have an equal amount of dissociated OH, but that NaOH will...

OK I get that now, it's pretty straight forward. Thanks.

Ok, thanks. Is it standard that the concentrate solution, which is to be diluted, will be already calculated in w/w? It's 500ml ~18M. If I take 5g of the concentrated HS2O4, count 0.175ml of it as being H2O content (averaging 95-98% as 96.5%), then add 91.5ml H2O, will I then have a ~5% HS2O4...

Hi! I've got a beginner question. I'd like to know what quantities are required to make a couple solutions, but I'd also like to understand how the calculations are made. I have 95-98% H2SO4 and 28-30% NH4OH, and I'm attempting to figure out the values to make 100ml of 5% H2SO4 w/w and also...
