<u>Answer:</u> The number of ions dissociated are
<u>Explanation:</u>
We are given:
pH = 2.07
Calculating the value of pOH by using equation, we get:
To calculate hydroxide ion concentration, we use the equation to calculate pOH of the solution, which is:
We are given:
pOH = 11.93
Putting values in above equation, we get:
To calculate the number of moles for given molarity, we use the equation:
Molarity of solution =
Volume of solution = 1243 mL = 1.243 L (Conversion factor: 1 L = 1000 mL)
Putting values in above equation, we get:
According to mole concept:
1 mole of a compound contains number of particles
So, number of
will contain =
number of ions
Hence, the number of ions dissociated are
