2 Stationary ions can NOT Dissolving an Ionic ElectrolyteThe dissolving of an ionic electrolyte.All salts are ionic electrolytes!Hydroxide bases are ionic electrolytes!+―+―Stationary ions can NOTconduct electricityFree moving ions canconduct electricity
3 Dissolving an Ionic Electrolyte Ex. (1) Write the dissolving reaction for each of the following ionic electrolytes.NaCl(s) → _____________________________BaCl2(s) → ____________________________Sr(OH)2(s) → __________________________+1-11+1-1H2O1Na+1Cl(aq)(aq)+2-12+H2O1-11Ba+2Cl(aq)(aq)+2-1H2O2+1-11Sr+2OH(aq)(aq)
5 Dissolving an Ionic Electrolyte Ex. (2) Which of the following sodium chloride samples is incapable of conducting electricity?(1) NaCl(s) (3) NaCl(aq) (2) NaCl(l) (4) NaCl(g)Ionic electrolytes will conduct electricity NOT only in the aqueous phase BUT also in the liquid and gases phases because the ions are free to move around!
