CHEM HELP PLEASE???!!! A solution containing ions of an unknown element X is divided into 3 samples. Identify X.?(multiple choice!)
A solution containing ions of an unknown element X is divided into 3 samples. The following tests were performed on samples of the solution.
Sample Test Observation
1 Add H+ (aq) No Change
2 ADD OH-(aq) No Change
3 Add SO4-2 (aq) No Change
A. Pb + 2 (aq) B. Al + 3 (aq) C. Ba +2 (aq) D. Na + (aq) E. CO3 -2 (aq)
Can you please help me? I need to learn why the correct answer is correct. I am just not sure how what to look for when trying to solve this. Is the fact there is no reaction for all three samples important? I think it is.
Thank you so much!
