The subscript "aq" indicates that a substance is in aqueous solution, meaning it is dissolved in water. This notation is commonly used in chemical equations and formulas to specify the state of the substance.
I'm assuming that 2 is supposed to be a subscript, which would make that a negatively-charged ion consisting of two sulfur atoms. The aq means "aqueous" which means the ion is dissolved in water.
The symbol for a substance in a water solution is typically written as the chemical formula of the substance followed by "(aq)" to indicate it is in an aqueous solution. For example, the symbol for sodium chloride in water solution would be NaCl(aq).
In a chemical equation, the subscript (aq) after a molecule means that it is aqueous. An aqueous solution is a solution in which the solvent is water.Example: CN-(aq), H2CO3(aq)It represents that the ionic state is only in the water (solute); Latin 'aqua' is waterIt stands for "aqueous", and means it's dissolved in water.
The ionic equation for the reaction between magnesium perchlorate (Mg(ClO4)2) and copper(II) chloride (CuCl2) is: Mg(ClO4)2 (aq) + CuCl2 (aq) -> MgCl2 (aq) + Cu(ClO4)2 (s) The net ionic equation is: Mg2+ (aq) + 2ClO4- (aq) + Cu2+ (aq) + 2Cl- (aq) -> Mg2+ (aq) + 2Cl- (aq) + Cu2+ (aq) + 2 ClO4- (s)
The equation for the reaction between zinc nitrate and cupric nitrate is: Zn(NO3)2 + Cu(NO3)2 -> Cu(NO3)2 + Zn(NO3)2
