Suppose that a chemist is mixing two acid solutions, one of

30% concentration and the other of 40% concentration. Which of the following concentrations could not beobtained?

32%,

34%,

38%,

43%

Step 1

The two acid solutions are given, one is of 30% concentration and the other is of 40% concentration.

Step 2

From options, it is seen that three concentrations lie within the range 30% to 40%, and one concentration is more than 40%.

Step 3

It is known that when two solutions of different concentrations are mixed, the ne...
