Question

The conductivity of a saturated solution of $$Ag2C2O4$$ is $$4$$×$$10$$−$$5$$ S cm−$$1$$ at $$25$$°C. Conductivity of water is $$6$$×$$10$$−$$8$$ S cm−$$1$$. What is the approximate molar conductivity of $$C2O42$$− ion at infinite dilution, given molar conductivity of  $$Ag+$$ ions at infinite dilution is $$62$$ S $$cm2/mol$$ and $$KspAg2C2O4=3.2$$×$$10$$−$$11$$

Infinity Learn · Accepted Answer

$$Ksp=4S3=3.2$$×$$10$$−$$11$$⇒$$S=2$$×$$10$$−$$4$$∧$$0=$$χ×$$1000s2$$×$$62+x=4$$×$$10$$−$$5$$×$$10002$$×$$10$$−$$4=20$$⇒$$x=76$$
