Explanation To record the given data Concentration of NaOH is 0 .167M in 500mL Concentration of HCOOH is 0 .100M in 500mL The given data is recorded as such. To calculate moles of NaOH and HCOOH M o l e s N a O H = 0.500 L × 0.167 m o l 1 L = 0.0835 m o l M o l e s H C O O H = 0.500 L × 0.100 m o l 1 L = 0.0500 m o l The number of moles of NaOH and HCOOH is calculated by converting given moles to one litre. To calculate concentration of Na + , HCOO - , OH - , H + HCOOH ( aq ) +NaOH ( aq ) → HCOONa ( aq ) +H 2 O ( l ) Initial concentration ( mol ) : 0 .0500 0 .0835 0 Change in concentration ( mol ) : -0 .0500 -0 .0835 +0 .0500 Final concentration ( mol ) : 0 -0 .0335 0 .0500 The total volume of solution is 1L(500 mL+500 mL=1000 mL) [OH - ] = 0 .0335 mol 1 .00 L = 0 .0335 M [Na + ] = (0 .0335 + 0 .0500) mol 1 .00 L = 0 .0835 M [H + ] = K w [OH - ] = 1 .0 × 10 -14 0
