Question

What s the concentration of hydrogen ion or hydroxide ion for pure water at 25 degree celsius?​

Answer 1

Answer:

7

Explanation:

With water and in the absence of foreign materials, activity equals molar concentration and [H+] equals [OH−] as required by electroneutrality, and the product at 25°C equals Kw or 10–14. These conditions mean that {H+} = {OH−} = 10− 7, and the pH equals 7, which is considered the “neutral” pH for water.

Answer 2

Answer:

With water and in the absence of foreign materials, activity equals molar concentration and [H+] equals [OH−] as required by electroneutrality, and the product at 25°C equals. These conditions mean pH is 7, which is considered the “neutral” pH for water.
