# Sodium permanganate from manganese dioxide and sodium hypochlorite

This page states that sodium permanganate can be formed by the reaction of manganese dioxide with sodium hypochlorite and sodium hydroxide:

$$\ce{2 MnO2 + 3 NaClO + 2 NaOH -> 2 NaMnO4 + 3 NaCl + H2O}$$

I assume sodium carbonate ($\ce{Na2CO3}$) will also function in this reaction as a substitute for $\ce{NaOH}$.

Does this reaction take place at standard conditions, or are increases in temperature/pressure etc. required? Approximately how long will it take (at STP)? Also, will sodium carbonate be sufficient, or is sodium hydroxide required?

• I wouldn’t be too sure about the carbonate working. It may well be too weak a base …

• Different question: I am slightly confused about the home-experiment tag. Are you planning to do this at home? If so, adding a note to the question would be great.

• @Jan I added the home-experiment tag because this is a small experiment which can easily happen at home (bleach, batteries, baking soda). Jun 21 '16 at 0:01
