In the following ionic equation which are the spectator ions Ag aq NO3-aq Na aq I-aq --- Na aq NO3-aq AgIs?
spectator ions are: Na and NO3
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.
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+].
Silver ions react with thiocyanate ions as follows?
Ag+ (aq) + SCN- (aq) ----> AgSCN (s)
What forms when an acid and a base neutralize each other?
when the acid reacts with the base ,the H+ ions are given out from the acid and OH- ions from the base. they react together to form water and the residue salt is also produced. when all the number of H+ ions react with the appropriate number of OH- ions,they neutralize each other. for example: when certain amount of hydrochloric acid is added to sodium carbonate(base),they neutralize each other and water and salt(sodium chloride ,in this case) is given out.
Solutions characterized by the formation of hydroxide ions OH are?
Alkaline. Like Calcium Hydroxide, Potassium Hydroxide, etc.

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.

How do you solve ionic equations?
An ionic equation can be solved by: 1)Writing and balancing the given equation (if necessary) eg: 2Na(s)+2HCl(aq) --> 2NaCl(aq)+H2(g) 2) Split the ions (only ions that are aqueous are split) eg: 2Na(s)+2H(aq)+2Cl(aq) -->2Na(aq)+2Cl(aq)+H2(g) 3) Cancel the spectator ions(spectator ions are ions which remain in their original state after the chemical reaction) eg: 2Na(s)+2H+2Cl(aq) --> 2Na(aq)+2Cl(aq)+H2(g) 4)Write the balanced ionic equation: eg:2Na(s)+2H(aq) -->2Na(aq)+H2(g)
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.
What are the spectator ions in the reaction 2koh aq h2so4 aq 2h2o l k2so4 aq?
K+ and SO42-
What can be added to a solution of Cu2 (aq) Mg2 (aq) and Sr2 (aq) ions to precipitate the Sr2 (aq) ions but not the others?
Add a sodium hydroxide solution; copper and magnesium hydroxides are insoluble. Strontium hydroxide is low soluble.
What is the chemical equation representing how water split into hydrogen ions and hydroxide ions?
The corresponding reaction to the equilibrium is; H2O(l) <-> H+(aq) + OH-(aq) or another interpretation is; 2H2O(l) <-> H3O+(aq) + OH-(aq)
