zinc nitrate , zinc carbonate , copper(II) nitrate and copper(II) carbonate .
Daripada jadual di atas, kesan haba ke atas garam boleh digunakan untuk mengenal garam plumbum(II) nitrat , plumbum(II) karbonat ,
zink nitrat , zink karbonat , kuprum(II) nitrat dan kuprum(II) karbonat .
– Confirmatory test for other cations and anions is carried out by Confirmatory Tests for Anions and Cations
Ujian pengesahan untuk kation dan anion lain boleh dijalankan dengan menggunakan Ujian Pengesahan Anion dan Kation.

Conf rmatory Tests for Cations
Ujian Pengesahan bagi Kation

1 Chemical tests is conducted for confirmation of cations in aqueous form.
Ujian-ujian kimia dijalankan bagi pengesahan kation dalam bentuk akueus.
2 Confirmatory test is carried out by adding a small amount of sodium hydroxide solution / ammonia solution followed
by excess sodium hydroxide / ammonia solution to the solution contains the cation.
Ujian pengesahan dijalankan dengan menambah sedikit larutan natrium hidroksida / larutan ammonia diikuti dengan larutan natrium
hidroksida / larutan ammonia berlebihan kepada larutan yang mengandungi kation.
