Is HCI(aq) is added to a basic solution will the pH increase or decrease or stay the same?
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.
What are the spectator ions?
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.
In the following ionic equation which are the spectator ions Ag aq NO3-aq Na aq I-aq --- Na aq NO3-aq AgIs?
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.
Does the concentration of an acid or base refer to the presence of H3O plus ions in solution?
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+].
What kind of reaction is Kl(aq) plus AgNO3(aq) Agl(s) plus KNO3(aq)?
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?
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).
When solutions NACl and AgNO 3 are mixed what precipitate forms?
NaCl(aq) + AgNO3(aq) = AgCl(s) + NaNO3(aq) - so the precipitate is white silver chloride.
Is HCI(aq) is added to a basic solution will the pH increase or decrease or stay the same?
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.
7. Write chemical equations for the ion-forming reactions of the strong and weak bases in water. Identify the common ion that is produced in basic solutions.?
Strong bases, like sodium hydroxide (NaOH), completely dissociate in water to form hydroxide ions: [ \text{NaOH (s)} \rightarrow \text{Na}^+ (aq) + \text{OH}^- (aq). ] Weak bases, such as ammonia (NH₃), partially ionize in water: [ \text{NH}_3 (aq) + \text{H}_2\text{O} (l) \rightleftharpoons \text{NH}_4^+ (aq) + \text{OH}^- (aq). ] In both cases, the common ion produced in basic solutions is the hydroxide ion (OH⁻).

What are the spectator ions of AgC2H3O2 and CaCl2?
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.
An inorganic acid dissociates in water?
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.
What ions are present in sodium sulphate solution?
Dissolving in water (aq):Na2SO4 --> 2(Na+)aq + (SO42-)aq
In the following ionic equation which are the spectator ions Ag aq NO3-aq Na aq I-aq --- Na aq NO3-aq AgIs?
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.

What can be added to a solution of OH- (aq) S2- (aq) and SO42- (aq) ions to precipitate the OH- (aq) ions but not the others?
Add a solution of magnesium chloride; magnesium hydroxide is not soluble in water.
What is 2OH- (aq)?
2OH⁻ (aq) represents two hydroxide ions in an aqueous solution. Hydroxide ions are negatively charged and consist of one oxygen atom bonded to one hydrogen atom (OH⁻). In water, these ions can contribute to the solution's alkalinity, making it basic. The presence of hydroxide ions is common in strong bases, such as sodium hydroxide (NaOH).
