1.	Which of the following will produce the highest risein temperature?
Answer» 67 mL of 1M NaOH `+`33 mL of 0.5M `H_(2)SO_(4)` 33 mL of 1 M NaOH `+`67 mLof 0.5M `H_(2)SO_(4)` 40 mL of 1 M NaOH`+` 60 mL of 0.5 M `H_(2) SO_(4)` 50 mL of 1 M NaOH `+` 50 mLof 0.5M `H_(2)SO_(4)` Solution :0.5M `H_(2)SO_(4) -= 1NH_(2)SO_(4)`. HENCE,completeneutralization will TAKE placeonly in (d) where 50 mL OF1 MNaOH `(= 1N NaOH)` willneutralize 50 mLof0.5 M`H_(2)SO_(4)(1 N H_(2)SO_(4))`. Thus HEAT evolved will be maximum and so rise in temperature will be highest.
