In this reaction, the acid donates an H ion.2H(aq) 2OH-(aq) 2H2O(l) (because they are all the same, the coefficients may be left out). (c) Solution: HNO3 is a strong acid. It completely ionizes to H and NO3 ions. Ba(OH)2 is a strong base.4.54 (a) Cu(s) HCl(aq) no reaction, since Cu(s) is less reactive than the hydrogen from acids. 2-OH(aq) H2O(l) 2H2O(l) Equilibrium lies to the right, i.e. on the product side. 5. You have two equimolar acidic solutions, one of11. Acid-base reactions. a) Write and equation for the acid-base reaction between ammonium ions and sulfate ions. Why does the reaction favour the reactants? NaOH (aq) Na(aq) OH(aq) An acid neutralizes a base H(aq) OH( aq) H2O(l). The Arrhenius Theory.

HF (aq) OH- (aq) reaction!Since ethylamine is a stronger base than benzoic acid is an acid, then in the formation reaction, the base wins out and the resultant solution of the salt must be basic.) 2. Classify the above as acids, bases, salts and molecular (covalent compounds) by making four lists.3Sr(OH)2(aq). The reaction of an acid and a base is called a neutralization reaction . Although acids and bases have their own unique chemistries, the acid and base cancel each others chemistry to produce a rather innocuous substance - water.HNO 3 (aq) and Ba(OH) 2 (aq). BA (aq). soluble salt. 2 H2O (l) water.З In a reversible acid-base reaction, both forward and reverse reactions involve H transfer H H.NaOH (aq) ОО Na (aq) OH (aq) З Unlike strong bases that contain OH , weak bases produce hydroxide by reacting with water. H2SO4(aq) NaOH(aq) NaHSO4(aq) H2O(l) The acidic salt sodium hydrogen sulfate is formed. - in a 1:2 ratio. Basic salts are formed by the reaction of polyhydroxy bases with less than the stoichiometric amount of acid. Example.

Ba(OH)2.HCl(aq) H(aq) Cl-(aq) NaOH(aq) Na(aq) OH-(aq). The one-way arrows here imply that the reverse reactions do not occur to any significant extent (Cl-(aq) is a really bad base and Na( aq) is a really bad acid). Ba(OH)2(aq) H2SO4(aq) --> BaSO4(s) 2H2O(l) As you perform the reaction you are going from an ion rich solution to basically water with a precipitate floating in it. The are no more ions to conduct the electricity so the conductivity will drop to the conductivity of water alone. An Arrhenius base is a species that dissociates in water to produce hydroxide ions, OH-(aq). An Arrhenius acid reacts with an Arrhenius base to produce a salt and water in a neutralisation (neutralization) reaction 1 Ba(OH)2(aq) H2SO4(aq) rarr BaSO4(s)darr 2H2O(l).How does Lewis define acids and bases?

Reminder: Water is amphoteric so can behave as either an acid or a base.e.g. Reaction of a metal cation with water: Fe3 6 H2O Fe(H2O)63 Fe( H2O)5(OH)2 H. 4) Basic Oxides: (basic anhydrides) basic oxides have metal cations Metal oxide water metal hydroxide ( base) sulphuric acid H2SO4 gives 2H(aq) and SO42(aq) ions.calcium hydroxide Ca(OH)2 gives Ca2(aq) and 2OH(aq) ions. Note: an alkali is a base soluble in water.the spectator ions are Ba2 and NO3. a) A base accepts a proton from water in the base dissociation reaction: C5H5N( aq) H2O(l) OH-(aq) C5H5NH(aq).A salt derived from a strong base and a weak acid produces a basic solution. Na does not react with water CO32-(aq) H2O(l) HCO3-(aq) OH-(aq). So in this case H2SO4(aq) and Ba(OH)2(aq) must be written as aqueous ions and BaSO4(s) and 2 H2O(l) remains in their molecualr form.So the net ionic equation and the ionic equaton are the same.
