Kuch to gadbad hai..👌😂
So the story for this pic is - 
We were doing experiment to check the presence of radical in the given salt.
Actually a known salt. 😋
We became very frustrated when even the third time results were exactly opposite to our predictions. 😕
Then… And just then.. I saw the box of salt.
It was ‘sulphite’ and we were trying to detect ‘sulphide’. 😂😂😂
