just got
stabilized vitamin c , so the Ph value was measured in order to adjust the alkalinity to higher than 3.5. to request a notification number. But when using paper to measure Ph. Why is Ph around 4.5? Is it like this for every lot? or each Lot.ph is not equal Actually, when I read the details, I saw that the Ph would be at 2-3. Must add alkali to request a notification number But now it measures 4.5 Please answer me where I am wrong. Or do you have to use something to measure ph in order to get an exact number?
