Question

if ph of distilled water is 85 degreee celsius is 6.8 then predict its nature if temp.​

Answer 1

Answer:

Nature = Neutral

Explanation:

Pure water will always remain neutral despite pH

This is because for a solution to be neutral $[H^{+}] = [OH^{-}]$

pH = 7 is the criterion for neutrality ONLY at 25-degree celsius

This is because pH = $-\log[H^{+}]$ and the dissociation of water into ions increases with temperature so pH decreases. The concentration of bot ions increases equally.
