Question
Sodium hydroxide, NaOH, is a strong base. What is the hydroxide ion concentration in a 0.2M sodium hydroxide solution?Multiple choice question.0.1M0.3M0.4M0.2M
Solution
The concentration of hydroxide ions in a sodium hydroxide solution is equal to the concentration of the sodium hydroxide itself. This is because one molecule of sodium hydroxide (NaOH) dissociates into one sodium ion (Na+) and one hydroxide ion (OH-) in solution. Therefore, in a 0.2M sodium hydroxide solution, the hydroxide ion concentration is also 0.2M.
