MCQ
Given below are two statements :
Statement $(I) :$ A Buffer solution is the mixture of a salt and an acid or a base mixed in any particular quantities.
Statement $(II) :$ Blood is naturally occurring buffer solution whose pH is maintained by $H _2 CO _3 / HCO _3^{\ominus}$ concentrations.
In the light of the above statements, choose the correct answer from the options given below.
  • A
    Statement I is false but Statement II is true
  • B
    Both Statement I and Statement II is true
  • C
