Does sodium metal react with potassium hydroxide solution?

No. It would be a displacement reaction and this only works if the metal is higher in the activity series than the one it wants to displace. Given that potassium is the highest ranked metal (sodium second), there should be no reaction. Look up activity series for more information.

Na metal will react with a KOH solution because it reacts with the H2O of the solution. It does not displace K^+ as Supa has written.
2Na + 2H2O ==> H2 + 2NaOH

There seems to be some conflicting information here. Let me clarify the reaction between sodium metal and potassium hydroxide solution for you.

Sodium metal does react with potassium hydroxide (KOH) solution. The reaction can be represented as:

2Na(s) + 2KOH(aq) -> H2(g) + 2NaOH(aq)

In this reaction, sodium metal displaces potassium from potassium hydroxide, resulting in the formation of hydrogen gas (H2) and sodium hydroxide (NaOH) in solution.

So, to summarize, sodium metal does react with potassium hydroxide solution to produce hydrogen gas and sodium hydroxide.

To determine whether sodium metal reacts with potassium hydroxide (KOH) solution, we can use the activity series. The activity series is a list of metals in order of their reactivity, with the most reactive metal at the top and the least reactive metal at the bottom.

In this case, sodium is less reactive than potassium. This means that sodium cannot displace potassium in a reaction. Therefore, there should not be a displacement reaction between sodium metal and potassium hydroxide solution.

However, it's important to note that sodium metal can react with water (H2O) to produce hydrogen gas (H2) and sodium hydroxide (NaOH). The reaction is as follows:

2Na + 2H2O -> H2 + 2NaOH

In this reaction, sodium metal reacts with water to form sodium hydroxide and release hydrogen gas. This reaction does not involve displacing potassium ions and is unrelated to the activity series.

To verify this information, you can look up the activity series, or you can conduct the experiment yourself and observe whether a reaction occurs between sodium metal and potassium hydroxide solution. Always be cautious and follow appropriate safety precautions when working with chemicals.
