Hi,
You are using a w/v to calculate your NaOH conc. - where the weight of the solute is not additive to the weight of the solvent. But here, on the soap calc they (we) use a w/w calulation where the weight of both the solute and the solvent is additive. Thus the info the soap cal gave you is...
Your right - I work in a laboratory, my assumption was that anyone using sodium hydroxide would have knowledge such as safey issues, did not realize. I wanted to share as the information I have receive from this forumn has been very beneficial to my quest in soap making and I wanted to give...
