Question

For the chemical reaction, $NaOH$ + $K$ $\Rightarrow$ $KOH$ + Na Choose the right option.

• A. Na is oxidised and K is reduced
• B. Both K and Na are reduced
• C. Na is reduced and K is oxidised
• D. Both K and Na are oxidised

Answer 1

The correct option is C

Na is reduced and K is oxidised

Na is reduced and K is oxidised

Na gains back the electrons it lost during the formation of NaOH, and reduces to Na metal. Potassium K, on the other hand displaces Na from NaOH and gets oxidised by losing single electron to hydroxide ion and finally forms KOH.
