Question

Without going into systematic mixture analysis, the test that can identify $B{a}^{2+},C{a}^{2+},S{r}^{2+}$ is known as flame test.

If true enter 1, else enter 0.

Answer 1

Flame Test can be used to identify the cations as follows:
$B{a}^{2+}$ : ion gives apple green colour in the flame.
$C{a}^{2+}$ : ion gives brick red colour in the flame.
$S{r}^{2+}$ : ion gives crimson red colour in the flame.
