H+ (or better: H3O+) and Cl- ions.
Names are respectively: proton , hydronium ion, chloride ion.
When table salt (NaCl, sodium chloride) is dissolved in water, it'll form positve sodium (Na+) ions and negative chloride (Cl-) ions in equal amounts.
salt and water ions
H+ and OH- ions are formed.
OH- and H+
H+ and OH-
Ca(NO3)2 dissociates into Ca^2+ ion and 2 NO3^- ions
Cobalt(II) nitrate dissociates as follows:Co(NO3)2 ==> Co^2+ + 2NO3^-
H2SO4 is an acid, not a metal and it does not contain any metals. In water it dissociates into H+ and SO42- ions with 1+ and 2- charges respectively.
Water containing dissolved Calcium ions (Ca2+) or Magnesium ions (Mg2+) react with soap to form scum.E.g: Calcium ions in hard water react with the stearate ions in soap solution to form scum.Ca 2+ (aq) + 2 stearate 1- (aq) >reacts to form> Ca(stearate)2 (s)Quite complicated but i hope that helps.
To find number of ions in a chemical formula, you must know how the molecule dissociates or ionizes. For example, the salt NaCl ionizes to Na^+ and Cl^- so there are 2 ions. But the salt CaCl2 ionizes into Ca^2+ and 2 Cl2^2, so there are 3 ions (1 calcium and 2 chloride).

Calcium chloride (CaCl2) is soluble in water, and simply dissociates into ions. Thus,CaCl2(s) + H2O(l) ==> Ca^2+(aq) + 2Cl^-(aq) + H2O(l)
Oxygen and 2 Hydrogen.Hence the H2O1

lose 2 electrons and form ions with a 2+ charge.

CaCl2 dissolves in water. Ca2+ and 2 Cl- ions form in water. The water does not change color. When the water is over-saturated with these ions, further dissolution will stop.
A strong electrolyte dissociates completely into ions in aqueous solution. When lead cyanide, a strong electrolyte, is put into water the cations and anions are surrounded by water molecules and the solid dissolves.Pb(CN)2(s) Pb2+(aq) + 2CN-(aq)We represent this state by the symbol "(aq)" to indicate that the ions are in aqueous solution.
Milk of magnesia is a solution of magnesium hydroxide (a white powder) in water. It is a base because when the powder is introduced into water, it partially dissociates (breaks up) into magnesium (Mg2+) and hydroxide (OH-) ions. Pure water contains an equal number of OH- ions and another ion called hydronium ions (H3O+). Because the milk of magnesia adds OH- ions to the water, there are now more OH- ions than H3O+ ions. This means you have a base. On the opposite end, if there are more H3O+ ions than OH- ions, which happens when you add vinegar or lemon juice to water, you have an acid. Hope that makes sense!
