1. Potassium hydrogen sulfate (KHSO4): H2SO4 donates a proton (H+) to KI, forming KHSO4.

2. Hydriodic acid (HI): The iodide (I-) from KI reacts with the acidic solution, resulting in the formation of hydrogen iodide (HI).

So, the products of the reaction between KI and H2SO4 are potassium hydrogen sulfate (KHSO4) and hydriodic acid (HI).
