MCQ
Which has the smallest size
  • A
    $N{a^ + }$
  • B
    $M{g^{2 + }}$
  • C
    $A{l^{3 + }}$
  • ${P^{5 + }}$

Answer

Correct option: D.
${P^{5 + }}$
d
(d) As the nuclear charge per electron is maximum in ${P^{5 + }}$. Therefore its size is smallest.

When $100 \ mL$ of $1.0 \ M \ HCl$ was mixed with $100 \ mL$ of $1.0 \ M \ NaOH$ in an insulated beaker at constant pressure, a temperature increase of $5.7^{\circ} C$ was measured for the beaker and its contents (Expt. $1$). Because the enthalpy of neutralization of a strong acid with a strong base is a constant $\left(-57.0 \ kJ \ mol ^{-1}\right)$, this experiment could be used to measure the calorimeter constant. In a second experiment (Expt. $2$), $100 \ mL$ of $2.0 \ M$ acetic acid $\left(K_a=2.0 \times 10^{-5}\right)$ was mixed with $100 \ mL$ of $1.0 M \ NaOH$ (under identical conditions to Expt. $1$) where a temperature rise of $5.6^{\circ} C$ was measured.

$2.$ The $pH$ of the solution after Expt. $2$ is
