In Alkaline solution we have chromates and in acidic solution, dichromates ? Explain.

Ph of an acidic solution is:

Isotonic solutions have

Which ion is produced in acidic solution?

An acidic solution contains……………..ions.

Isotonic solutions must have the same

Ammonia forms the complex ion [Cu(NH_3)_4]^(2+) with copper ions in alkaline solutions but not in acidic solution. The reason for this is

The chromate ion in acidic medium changes to ............. ion.
