My teacher told me KI(s, or aq) + H2O (l) yields K + I2 + KOH

I think the answer is KI yields H2 + I2 + KOH

Hi Dinorah Perry,

At the moment, I'm not exactly sure what you mean. You should write the whole question down to make it clearer.

Best,

Hi Kinorah Perry,

I think that you're right:
KI(aq) + H2O(l) Rightwards Arrow H2(g) + I2(s) + KOH(aq)

Best,
Laser
