Would xylitol be acidic or basic in solution?

Continuing from the previous answer by Quora User, the theoretical p K a of Xylitol is 12.7 (if those three sources I have found are correct, but let's still assume it is). This makes its K a be equal to 2.0 × 10 − 13 . read more

Assuming maximum solubility (~ [math]0.1 \text{ g cm}^{-3}[/math]), there will be 100 grams of Xylitol dissolved in a litre of water (or 0.657 mol of Xylitol), meaning the concentration is [math]0.657 \text{ mol dm}^{-3}[/math]. read more

The pH of a buffer solution will depend on the Ka of the weak acid and the ratio of the weak base to the weak acid. In general, if the Ka of the weak acid is greater than 1E-7, that buffer would be acidic, and if Ka is smaller than 1E-7, then it would be basic. read more

Calculate [OH−] given [H3O+] in each aqueous solution. Then tell if each one is acidic or basic. A. [H3O+] = 5.0×10−9 M B. [H3O+] = 8.3×10−9 M C. H3O+] = 5.3×10−3 M D. [H3O+] = 4.6×10−12 M E. [H3O+] = 6.7×10−4 M F. [H3O+] = 6.6×10−9 M 26. Calculate [H3O+] given [OH−] in each aqueous solution. Classify as acidic or basic. A. read more
