Get away the oxygen in the solution.At pH \u003d 7, manganese ions may be oxidized, generate mn (IV), and hydrolysis produces color
It should be MNO (OH) 2, which is the result of MN2+being oxidized by air.Only in the acidic environment can help the existence of MN2+, otherwise it must be hydrolyzed to mn (OH) 2 and then oxidize the oxygen in the air to MNO (OH) 2.
