🤓 Based on our data, we think this question is relevant for Professor McMills' class at OHIO.

Solution: Which of these statements are true for a neutral, aqueous solution at 25 degree C? More than one can be correct. a. pH = 7.00b. pOH = 7.00c. [H+] = [OH -]Which of these statements are true for a neutral, aqueous solution regardless of temperature? More than one can be correct. a. pH = 7.00b. pOH = 7.00c. [H+] = [OH -]

Problem

Which of these statements are true for a neutral, aqueous solution at 25 degree C? More than one can be correct. 

a. pH = 7.00

b. pOH = 7.00

c. [H+] = [OH -]

Which of these statements are true for a neutral, aqueous solution regardless of temperature? More than one can be correct. 

a. pH = 7.00

b. pOH = 7.00

c. [H+] = [OH -]

Solution
  • Recall that at 25oC, Kw or autoionization constant is equal to 1.0x10-14

  • This can be written as

Kw = [H+] [OH-]
