Question

Which of the following solution will have pOH equal to 11 at 298 K ? (A) 1 × 10-11 M HCl (B) 1 × 10-3 HC1 (C) 1 × 10-3 NaOH (D) pOH of solution cannot be 11

pOH is 11 for this solution whose pH is 3. Thus, 1 × 10-3 M HCl will have pOH = 11

Q. Which of the following solution will have pOH equal to 11 at 298 K ?

$1 \times 1 0^{- 11} M H Cl$

$1 \times 1 0^{- 3} H C 1$

$1 \times 1 0^{- 3} N a O H$

pOH of solution cannot be 11

$pO H$ is $11$ for this solution whose $p H$ is $3$ . Thus, $1 \times 1 0^{- 3} M H Cl$ will have $pO H = 11$

Q. Which of the following solution will have pOH equal to 11 at 298 K ?

1×10−11MHCl

1×10−3HC1

1×10−3NaOH

pOH of solution cannot be 11

pOH is 11 for this solution whose pH is 3. Thus, 1×10−3MHCl will have pOH=11

$1 \times 1 0^{- 11} M H Cl$

$1 \times 1 0^{- 3} H C 1$

$1 \times 1 0^{- 3} N a O H$

$pO H$ is $11$ for this solution whose $p H$ is $3$ . Thus, $1 \times 1 0^{- 3} M H Cl$ will have $pO H = 11$
