“...occurred when too much sodium permanganated the water.”
Couldn’t pass chemistry, so had to go to j-school.
Still can’t tell a verb from a noun.
So too much sodium was permitted into the water and permanganated it. (I hate it when that happens!) Luckily it isn’t permanent. Although I presume it happens periodically.
Oh, so THAT’S it! Sodium pomegranate in the water.
