Question: ptyalin is acidic or basic?
Answer: The optimum conditions for ptyalin activity are a pH range of 5.6–6.9, a temperature of 378C, and the presence of certain anions and activators, such as chloride, bromide, and iodide. PH of saliva is 6.8 and it is acidic in medium..but if it it's more than 6.8 then it is basic..and more than 7.0 it is neutral.
