Another Example Example 1B. Calculate the volume of 6 M NaOH required to react COMPLETELY with 2 mmole of Methyl salicylate, how much (in mls) of 6 M NaOH was in excess of the theoretical amount required if you had used 2.5 ml NaOH (2 pts) Show your work (3 points)

Answer 1

Reaction The-che + NaOH de na MW : 152.149 mol +H2O ME C&H 803 I mole of Haon is required to hautsalise Imole of methyl sonicylate Given molarity of Moon = 6 m (M) Molarity of methyl soyjcylate = 2 mmol. (M₂) = 0.002 molar In case of mettyl salicylate concenpation 0.002 molar complete solution has volume I litre le 1000ml Apply the formula Mv Mooz x 1000 6 x V 0.002 x 200 V = 0.002 x 1000 • = 0.3333 mil Therefore 2 monol solution of methyl salicylate I require 0.3333 ml GM Naon to neutbalise ... Theoretical amount required = 0.3333 m/ If 2. 5ml Naon of om is added the excess theoretical amount is .. Excess theoretical amouk - 25 -0.3333 2.160 ml ". Excess theoretical amount of om naon 2.160 ml.
