So, we recently did a practical in my A-Level chemistry and we had a "Solution A" and some other chemicals. We added a few drops of each chemical to Solution A and wrote down our observations. I would love to know what this chemical is, but it doesn't relate to any of the identification tables in our chemistry book.

So,

 

Sodium Hydroxide - No visible changes

Sulfuric acid - White precipitate

Potassium Chromate (VI) - Yellow precipitate we also added Hydrochloric acid to this and then it turned clear and deep orange colour

Silver nitrate + Nitric acid - No visible changes

Sodium carbonate - White precipitate

I would be very happy if you could help me or point me in the right direction.

Thanks for this. Didn't really come in handy but I think I did well in the exam and thanks for the help.

Possibly a barium compound or lead compound. There could be other possibilities I'm forgetting.

By using the color of the precipitate and the chemical that you added, you will be able to determine the solution.
