CHEMICAL REACTION IN ELECTROLYTE SOLUTIONS SOLUTIONS STIKIOMETRI 

Acid-base reaction (neutralization reaction).Acid-base reaction or neutralization reaction is the reaction between the acid (H +) and a base (OH-) produced a neutral H2O.Adapaun example neutralization reaction is as follows:
1. Reactions: Acid + base -> salt + waterHNO3 (aq) + KOH (aq) -> KNO3 (aq) + H2O (l)H2SO4 (aq) + Ca (OH) 2 (aq) -> CaSO4 (aq) + H2O (l)
 2. Reaction: Oxide + Acid Tongue -> Salt + Water2HCl (aq) + CaO (s) -> CaCl2 (aq) + H2O (l)2HNO3 (aq) + Na2O (s) -> Na (NO3) 2 (aq) + H2O (l)
 3. Reactions: Ammonia + Acid -> SaltHCl (aq) + NH3 (g) -> NH4Cl (aq)H2SO4 (aq) +2 NH3 (g) -> (NH4) 2SO4 (aq)Ammonia (NH3), including bases that form molecular compounds that are distinguished from the other two types of bases, ie, ionic compounds that can release OH-ions and okisda bases. There are other basic molecular compounds such as methylamine (CH3NH2) but the reaction is not common as ammonia.4. Reaction: Oxides of acid + base -> salt + waterSO3 (g) + 2NaOH (aq) -> Na2SO4 (aq) + H2O (l)CO2 (g) + Mg (OH) 2 (aq) -> MgCO3 (aq) + H2O (l)Reaction crowding-MetalCrowding-metal reaction is a reaction in which the metal pressing of other metal cations or hydrogen in a compound. This reaction can take place if the metals are on the left of the metal / H which urged the Volta series. In this reaction, the reaction product in the form of metal deposition, gas, and water.Volta Series is a sequence of elements whose reduction potential is based on the data. The following are some elements that can be memorized by a potential reduction sequence:Li - K - Ba - Ca - Na - Mg - Al - Mn - Zn - Fe - Ni - Sn - Pb - (H) - Cu - Hg - Ag - Pt - AuAs an example of crowding-metal reactions are as follows:1. Reactions: 1 + Metal Salt 1 -> 2 + Metal Salt 2Zn (s) + CuSO4 (aq) -> ZnSO4 (aq) + Cu (s)2AL (s) + 3FeSO4 (aq) -> Al2 (SO4) 3 (aq) + 3Fe (s)Cu (s) + Na2SO4 (aq) -> no reaction because Cu is on the right row voltaic2. Reaction: Metal + Acid -> Salt + Hydrogen GasMg (s) + HCl (aq) -> MgCl2 (aq) + H2 (g)Zn (s) + H2SO4 (aq) -> ZnSO4 (aq) + H2 (g)Ag (s) + HCl (aq) -> Ag does not react due to the right of the voltaic series3. Reaction: Metal + Acid -> Salt + Water + Gas2Fe (s) + 6 H2SO4 (aq) -> Fe2 (SO4) 3 (aq) + 6 H2O (l) + 3SO2 (g)Cu (s) + 4HNO3 (aq) -> Cu (NO3) 2 (aq) + 2H2O (l) + 2NO2 (g)Metathesis reactions (Exchange Pair)Metathesis reaction is the reaction of the ion pair exchange two electrolytes.AB + CD -> AC + BDIn this reaction is at least one reaction product will form a precipitate, a gas, or a weak electrolyte. Gas can be derived from the decomposition of hypothetical substances (acids and bases hypothetical break down into gas and water) that are not as stable as the following:H2CO3 -> CO2 (g) + H2O (l)H2SO3 -> SO2 (g) + H2O (l)NH4OH -> NH3 (g) + H2O (l)
 As an example of metathesis reactions (exchange partner) are as follows:1. Reaction: Acid salt 1 + 1 -> 2 + Acid Salt 2AgNO3 (aq) + HBr (aq) -> AgBr (aq) + HNO3 (aq)ZnS (s) + 2HCl (aq) -> ZnCl2 (aq) + H2S (aq)
 2. Reaction: Salt 1 + Bases 1 -> Salt 2 + 2 BasesCuSO4 (aq) + 2NaOH (aq) -> Na2SO4 (aq) + Cu (OH) 2 (aq)NH4Cl (aq) + KOH (aq) -> KCl (aq) + NH4OH (aq)
 3. Reaction: Salt Salt 1 + 2 -> 3 + Garam Garam 4AgNO3 (aq) + NaCl (aq) -> AgCl (aq) + NaNO3 (aq)2KNO3 (aq) + MgCl2 (aq) -> 2KCl (aq) + Mg (NO3) 2 (aq)
