Now I use .1 NaOH. Calls for only 5 ml of sample. (And can be diluted with distilled water without hurting results) And NaOH used x 1.5. So if 4ml of NaOH needed then * 1.5 = 6 g/L Titratable acid.
Here's the reference I use.
i understood the point completely now every thing make sense
thank you so much

I just recently switched from .2 to .1 NaOH. There was at least one occasion where I was sweating my TA dropping like crazy. Glad I procrastinated on the adjustment, because I just forgot to multiply by 1.5
