Question

The________ cation will precipitate after the_________ step. Then the _________cation will precipitate after the________ step.

a. fourth
b. first
c. second
d. third
e. Al^3+
f. Sn^4+

Answer 1

f. Sn^4+

c. second

e. Al^3+

d. third

Step-by-step explanation:

This question comes from a quantitative analysis showing the flowchart of a common scheme for identifying cations.

Now, from the separation scheme, Let's assume that Sn⁴⁺ & Al³⁺ were given; Then, Yes, the separation will work.

However, there will be occurrence of precipitation after the 1st step1.

So, the Sn⁴⁺ cation will precipitate after the second step. Then the Al³⁺ cation will precipitate after the third step.
