Untuk menyelesaikan soal diatas perlu diperhatikan hal-hal berikut. Secara umum rumus pembentukan senyawa ionik yaitu: Tata nama senyawa asam yaitu kation mengacu untuk "asam", sementara anionnya diberi akhiran "ida" jika biner, dan jika anion poliatom maka mengikuti nama khusus anion poliatom tersebut. Tata nama senyawa ionik dengan kation golongan utama yaitu indeks atom tidak disebutkan, nama kation ditulis terlebih dahulu, diikuti nama anion. Jika senyawa ionik biner, maka anion diberi akhiran "ida". Dengan demikian, rumus senyawa yang terbentuk beserta nama-namanya pada soal adalah sebagai berikut. Anion Anion Anion Anion Anion Jadi, tabel secara lengkap adalah sebagai berikut. .

Untuk menyelesaikan soal diatas perlu diperhatikan hal-hal berikut.

  • Secara umum rumus pembentukan senyawa ionik yaitu:


Senyawa space biner space colon X to the power of a plus end exponent space plus space Y to the power of b minus sign end exponent space rightwards arrow space X subscript b Y subscript a  Senyawa space poliatom space colon X to the power of a plus end exponent space plus space YZ to the power of b minus sign end exponent space rightwards arrow space X subscript b open parentheses YZ close parentheses subscript a

 

  • Tata nama senyawa asam yaitu kation H to the power of plus sign mengacu untuk "asam", sementara anionnya diberi akhiran "ida" jika biner, dan jika anion poliatom maka mengikuti nama khusus anion poliatom tersebut.
  • Tata nama senyawa ionik dengan kation golongan utama yaitu indeks atom tidak disebutkan, nama kation ditulis terlebih dahulu, diikuti nama anion. Jika senyawa ionik biner, maka anion diberi akhiran "ida".

Dengan demikian, rumus senyawa yang terbentuk beserta nama-namanya pada soal adalah sebagai berikut.
