Ionic solid Na+A− crystallizes in rock salt type structure. 2.592g o – InterviewSolution

1.	Ionic solid Na+A− crystallizes in rock salt type structure. 2.592g of the ionic solid salt NaA is dissolved in water to make a 2 litre solution. The pH of this solution is 8. If the distance between the cation and the anion is 300pm, calculate the density of the ionic solid (in g/cm3) (Given: pKw=13,pKa[HA]=5,NA=6×1023)
Answer» Ionic solid $N a^{+} A^{-}$ crystallizes in rock salt type structure. $2.592 g$ of the ionic solid salt NaA is dissolved in water to make a 2 litre solution. The pH of this solution is 8. If the distance between the cation and the anion is $300 pm$ , calculate the density of the ionic solid $({in g/cm}^{3})$ (Given: $p K_{w} = 13, p K_{a} [H A] = 5, N_{A} = 6 \times 10^{23})$
