Q14 / 160 · AP EAMCET 2024 (20 May Shift 1) · Chemistry

$\mathrm{Ba}, \mathrm{Ca}, \mathrm{Sr}$ form halide hydrates. Their formulae are $\mathrm{BaCl}_2$, $x \mathrm{H}_2 \mathrm{O}, \mathrm{CaCl}_2 y \mathrm{H}_2 \mathrm{O}, \mathrm{SrCl}_2, \mathrm{zH}_2 \mathrm{O}$. The values of $\mathrm{x}, \mathrm{y}, \mathrm{Z}$ respectively are

  • Correct answer
    A
    $2,6,6$
  • B
    $8,6,2$
  • C
    $8,6,6$
  • D
    $6,4,2$

Solution

$\mathrm{BaCl}_2 \cdot 2 \mathrm{H}_2 \mathrm{O}, \mathrm{CaCl}_2 \cdot 6 \mathrm{H}_2 \mathrm{O}, \mathrm{SrCl}_2 \cdot 6 \mathrm{H}_2 \mathrm{O}$ so $x, y, z$ are $2,6,6$.

Hence, the correct answer is option: 'A'.
