Answer:
1- there are three positive ions
2- there are four negative ions
3- check below
Explanation:
1- I say three cations because there are 2 atoms of H (H has a charge of +1) and 1 atom of S (S has a charge of +6 in this compund) (cations are positive ions)
2- There are four anions because there are 4 atoms of O (O has a charge of 2- in this compound) (anions are negative ions)
3- Sorry, can you elaborate on the last question? I don't understand it.
