Question

A solution of sodium hydroxide (naoh) has a ph of 10. A 10 ml of this solution is mixed with 990 ml of water. The ph of the diluted solution is closest to

Answer 1

Explanation:

• A solution of sodium hydroxide (NaOH) has a pH of 10. 10 mL of this solution is mixed with 990 mL of water.
• 20.0 mL of 0.10 M hydrochloric acid (HCl) reacts with 20.0 mL of 0.30 M potassium hydroxide (KOH) solution.
• A 100 mL sample of helium exerts a pressure of 1 atm at 10°C.

Answer 2

Explanation:

A solution of sodium hydroxide (NaOH) has a pH of 10. 10 mL of this solution is mixed with 990 mL of water. 20.0 mL of 0.10 M hydrochloric acid (HCl) reacts with 20.0 mL of 0.30 M potassium hydroxide (KOH) solution. A 100 mL sample of helium exerts a pressure of 1 atm at 10°C.
