Cards in this set: Term Acid Definition a proton donor Term Base Definition proton acceptor Term conjugate Acid Definition formed by the addition of a proton to the reactant base base-add proton-->conj. acid Term conjugate Base Definition formed by the removal of a proton from the reactant acid acid--subtract proton--->conj. base Term Acids React with MEtals Definition acids will react with metals ABOVE hydrogen on the activity series to produce an ionic compound and H2 gas. Ex. 6HC2H3O(aq)+2Al(s)-->3H2(g)+2Al(c3H3O2)3(aq) Term Acids Reaction With Bases Definition neutralizes reactions to produce a new salt and water. Use Solubility RULES. Ex. HBr(aq)+KOH(aq)-->KBr(aq)+H2O(l) Term Acids Reaction with Metal Oxides Definition Produce a salt and water. Use Solubility RULES. Ex. H2SO4(aq)+MgO(s)-->MgSO4(aq)+H2O(l) Term Acids Reaction with Carbonates(CO3 2-) & Bicarbonates (HCO3 -) Definition These reactions produce a new ionic compound and carbonic acid. Carbonic acid is unstable and immediately go to CO2 & H2O. Use Solubility Rules. Ex. H2SO4(aq)+MgCO3(s)-->MgSO4(aq)+H2O(l)+CO2(g) Term Amphoteric Definition meaning they can either react as an acid or a base Term BASE reactions with Acids Definition neutralization reactions Term Reactions of BASES Definition 1. with acids=neutralization reaction 2. Hydroxides of certain metals such as zinc, aluminum and chromium are amphoteric. 3. Some amphoteric metals react directly with KOH & NaOH to produce hydrogen. Term SALTS Definition recall that salts are the produce of a neutralization reaction. Term STRONG ACIDS Definition HCl, HBr, HI, H2SO4, HClO3, HClO4, HNO3 Term STRONG BASES Definition Hydroxides of alkali metals and alkaline earth metals. Term ELECTROLYTES Definition Have Ions, Conduct electricity. ionic compounds are electrolytes. Term NON Electrilytes Definition Do not dissociate into ions in water, they are molecular compounds, do not conduct electricity. Term Strong Electrolytes Definition 100% dissociates into ions; all salts(ionic compounds) and Strong Acids and Bases. Term Weak Electrolytes Definition NOT 100% dissociated into ions in water, weak acids and bases, Nh3, Fe(OH)3, HNO2. *do not confuse with nonelectrolytes HC2H3O2. Term pH Definition water is amphoteric and reacts as follows: H2O+H2O-->H3O(hydronium)+OH-(hydroxide) The ionization of water at 25'C produces a hydrogen (hydronium) ion concentration of 1.0x10^-7 M and a hydroxide ion concentration of 1.0x10^-7 M. Term pH: the Greater the acidity the... Definition the greater the H+ the less the pH. pH less than 7 is acid. less OH-=greater pH Term pH: the less the Acidity the.... Definition less the H+, the greater the pH. pH greater than 7=Base. greater the OH-=less pH. Term pH: the acidity of the solution depends on the concentration of the hydrogen or hydronium ions. Definition Term Titrations Definition are neutralization reactions involving the mixing of an acid and a base to get a salt and water. Term Equivalence Point Definition the equivalence point in a neutralization reaction is where moles of base added are equal to the moles of acid in the beaker. Term Endpoint Definition where the indicator changes colors. it is an approximation of the equivalence point. Term Net Ionic Equations Definition show only the species that are involved with the chemical reaction. Term Spectator Ions Definition they are not directly involved with the chemical reaction. Term steps to writing a Net Ionized Equation Definition 1. Write the complete balanced equation including phases of each compound. 2. IONIZE everything that is an (aq)-put in proper coefficients. 3. Cancel out the spectator ions. 4. Write the equation you have left..this is the net ionic equation!!
