Yes, basic solutions can have (aq) ions. Basic solutions typically contain hydroxide ions (OH-) which can dissociate in water to form aqueous ions. The presence of these hydroxide ions increases the concentration of hydroxide ions in the solution, making it basic.
If you add HCl(aq) (hydrochloric acid) to a basic solution, the pH will decrease. This is because HCl is a strong acid that will react with the hydroxide ions present in the basic solution, forming water and chloride ions, which in turn lowers the overall pH of the solution.
Spectator ions, in a chemical reaction, are ions that don't take part in the overall reaction. For instance, consider the following reaction:Pb2+ (aq) + 2 NO3 (aq) + 2 K+(aq) + 2 I-(aq) ---> PbI2(s) + 2 K+(aq) + 2 NO3-(aq)The bolded and italicized compounds are spectator ions. They do not play an active role in the reaction. So, when these spectator ions are removed, we end up with a net ionic equation:Pb2+(aq) + 2 I-(aq) ---> PbI2(s)Source: College student in Chemistry, wrote these examples out of the book.
The spectator ions in this reaction are Na+ and NO3-. They remain unchanged on both sides of the equation and do not participate in the formation of the precipitate AgI.
An acid solution is a solution that contains more hydronium (H3O+) ions than hydroxide (OH-) ions. On the other hand, the reverse is true for a basic solution. Acidic solutions will have a pH less than 7 whereas basic solutions will have a pH greater than 7 by the equation pH=-log[H3O+].
This is a double displacement reaction where the cations and anions of the reactants switch partners to form new compounds. In this specific reaction, potassium ions (K+) from KI(aq) combine with nitrate ions (NO3-) from AgNO3(aq) to form KNO3(aq), while silver ions (Ag+) from AgNO3(aq) combine with iodide ions (I-) from KI(aq) to produce AgI(s).
Solutions characterized by the formation of hydroxide ions OH are basic or alkaline in nature. These solutions have a pH greater than 7. Common examples include sodium hydroxide (NaOH) and potassium hydroxide (KOH).
NaCl(aq) + AgNO3(aq) = AgCl(s) + NaNO3(aq) - so the precipitate is white silver chloride.
If you add HCl(aq) (hydrochloric acid) to a basic solution, the pH will decrease. This is because HCl is a strong acid that will react with the hydroxide ions present in the basic solution, forming water and chloride ions, which in turn lowers the overall pH of the solution.
2AgC2H3O2 (aq) + CaCl2 (aq) -> 2AgCl2 (s) + Ca(C2H3O2)2 (aq) 2Ag1+ (aq) + 2C2H3O21- (aq) + Ca2+(aq) + 2Cl1- (aq) -> 2AgCl2 (s) + Ca2+ (aq) + 2C2H3O21- (aq) In the reaction, both acetate (C2H3O2) and Calcium are aqueous in both the reactants and products, therefore they are the spectator ions.

When an inorganic acid dissociates in water, it breaks apart into its constituent ions. For example, when hydrochloric acid (HCl) dissociates, it forms hydrogen ions (H+) and chloride ions (Cl-) in the solution. This process is important for acids to exhibit their acidic properties in aqueous solutions.
Dissolving in water (aq):Na2SO4 --> 2(Na+)aq + (SO42-)aq
The spectator ions in this reaction are Na+ and NO3-. They remain unchanged on both sides of the equation and do not participate in the formation of the precipitate AgI.

Add a solution of magnesium chloride; magnesium hydroxide is not soluble in water.
When sodium dihydrogen phosphate (NaH2PO4) dissociates in water, it forms sodium ions (Na+) and dihydrogen phosphate ions (H2PO4-). The dissociation equation is: NaH2PO4 --> Na+ + H2PO4-. These ions are involved in various chemical reactions and play important roles in biological processes.
