Question
A given white crystalline salt was tested as follows:
It dissolved in water and the resulting solution of the salt turned blue litmus red. What conclusions can be drawn for the observation?
Solution 1
Since the salt solution turned blue litmus red hence the salt may be an acid.
Solution 2
White crystalline salt must be salt of Pb2+, Zn2+, Ca2+, Na+, K+
Notes
Students should refer to the answer according to their questions.
