a) Which of these statements are true for a neutral, aqueous solution at 25 °C?

pH =7.00

pOH =7.00

[H⁺] = [OH⁻]

b) Which of these statements are true for a neutral, aqueous solution regardless of temperature?

pOH = 7.00

[H⁺] = [OH⁻]

pH = 7.00

♦ Relevant knowledge

Acidic, Basic, and Neutral Solutions

Acidic solutions offer an extremely high amount of hydrogen ions. Basic solutions include solutions that have a the highest concentration of hydroxide ions. neutral solutions are those that have a concentration of both hydroxide and hydrogen ions is the same.

For neutral solutions. H *]=[OH] at any temperature. The value of Ky is 10-14 at 25°C. The relationship between Ky and concentrations hydronium ion & hydroxide is Ky = [H+][OH]=10-14 [H OH]=10-2 (neutral Solutions) The correct statement about a neutral, alkaline solution at 25°C is pH = 7.00, [OH] =-7.00 and (H “]=[OH–) The correct statement regarding a neutral, alkaline solution is pH = 7.00, [OH-] Because temperature changes, Ky’s value of Ky is not always equal to 7.
