For a weak acid HA the percentage of dissociation is nearly 1% at equilibrium. If the concentration of acid is 0.1 mol L−10.1\ \text{mol L}^{-1} then the correct option for its KaK_a at the same temperature is: 1×10−41 \times 10^{-4} 1×10−61 \times 10^{-6} 1×10−51 \times 10^{-5} 1×10−31 \times 10^{-3}

Multiple Choice Options

  • A 1×10−41\times10^{-4} 1 _ 1 0 _ 4
  • B 1×10−61\times10^{-6} 1 _ 1 0 _ 6
  • C 1×10−51\times10^{-5} 1 _ 1 0 _ 5
  • D 1×10−31\times10^{-3} 1 _ 1 0 _ 3

Step-by-Step Verified Solution

K a = C _ 2 K a = ( 0.1 ) _ ( 0.01 ) 2 K a = 1 _ 10 _ 5
