Approximately 1 mL of two clear, colorless solutions, 0.1 M Mn(NO3)2 and 0.1 M NaOH, were combined. Upon mixing, a brown precipitate formed. After centrifugation, the solution above the precipitate was found to be clear and colorless. Based on the these observations, determine if a reaction occurred. If so, write the balanced chemical equation. Hint : The precipitate formed is manganese (II) hydroxide
