Dear Friends,
My Question is why aluminium hydroxide reaction with hydrochloric acid AR grade give yellow solution.

Most of people say its due to iron impurity,but we used aluminium hydroxide contain less than 100 ppm iron to dissolve in hydrochloric Acid.

So,please give me some knowledge about this problem.

we want clear solution of aluminium hydroxide reaction with hydrochloric acid instead of yellow solution.

please help me in this direction.

No, the problem is the HCl. Technical grade contain a lot of iron.
