JEE Mains · Chemistry · STD 11 - 6.2. Equilibrium - II (icon Equilibrium)
An analyst wants to convert. \(1 L\,HCl\) of \(pH =1\) to a solution of \(HCl\) of \(pH 2\). The volume of water needed to do this dilution is \(......\,mL\). (Nearest Integer)
- A \(8000\)
- B \(9000\)
- C \(7000\)
- D \(6000\)
Answer & Solution
Correct Answer
(B) \(9000\)
Step-by-step Solution
Detailed explanation
\(\left(M_1 \times V_1\right)=\left(M_2 \times V_2\right)\) \(V _2=10\,L\) \(\text { Water added }=10-1\) \(=9 \text { Litre }\) \(=9000\,mL\)
