Question

Select the ion. Mg H+ HC2H3O2

Answer 1

The ion would be the hydrogen ion, H+, also known as a proton (this is because the hydrogen ion without an electron is simply reduced to a proton). This is because the H+ ion has a positive charge, a characteristic of ions. The hydrogen ion is often used in neutralization reactions involving water and a salt.

Hope this helps!
