Guida verificata passo dopo passo1
Identify the ions involved: potassium ion (K\^+) and sulfite ion (SO\_3\^{2-}).
Determine the charge on each ion: potassium has a +1 charge, and sulfite has a -2 charge.
Balance the total positive and negative charges to make the compound electrically neutral.
Since sulfite has a -2 charge, two potassium ions (each +1) are needed to balance one sulfite ion.
Write the formula by combining the ions with the correct subscripts: K\_2SO\_3.
