NEETChemistryIonic Equilibrium
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^- ) concentrations. In the light of the above statements, choose the correct answer from the options given below :
Options
- AStatement I is true but Statement II is false
- BBoth Statement I and Statement II are true
- CStatement I is false but Statement II is true
- DBoth Statement I and Statement II are false
Correct answer
C. Statement I is false but Statement II is true
Step-by-step solution
Buffer solution is a mixture of either weak acid / weak base and its respective conjugate. Blood is a buffer solution of carbonic acid H ₂ CO ₃ and bicarbonate HCO ₃⁻ Statement 1 is false but Statement II is true.
