1.	9.8g of an acid of molecuar weight 98 was neutralised by 200ml of one normal caustic soda. What is thebasicity of the acid?
Answer» Solution :NUMBER of milli EQUIVALENT of BASE `=200xx1=200meq`. Number of milli equivalent of acid =200m. EQ 200 milli equicalent of acid =? Equivalent weight of acid `=(9.8xx1000)/(200)=49` Basicity of acid `=("Molecular weight ")/("Equivalent weight")=(98)/(49)=2`
