In an experiment to measure the pH values of solutions, a student placed strips of universal indicator paper in four beakers containing solutions A, B, C and D. The colour of universal indicator paper in these solutions is as shown below :

The solution having lowest pH value is:
(1) A (2) B
(3) C (4)D
"

Correct answer: (3) C

Explanation: The universal indicator shows red colour for strong acids, it changes from orange to yellow for acids and from blue to indigo in the presence of bases. On the pH scale, acids have the lowest value. Hence, the solution having the lowest pH is the orange solution. i.e solution C.

In an experiment to measure the pH values by using a universal indicator, a student found that the pH values of four given solutions A, B, C, and D are 10, 6, 2, and 14 respectively. The solution which will require the maximum volume of sodium hydroxide solution for complete neutralisation is solution :(1) A (2) B (3) C (4) D
A student was given four unknown solutions in test-tubes marked A, B, C and D and asked to test them with universal indicator solution. He observed that on putting universal indicator solution, the solutions A, B, C and D turned blue, orange, green and red respectively. The test-tube which contains sodium chloride solution is :(1) A (2) B (3) C (4) D
Here are some results of solutions tested with universal indicator paper:
The pH values of five solutions A, B, C, D and E are given below:
A student was given three solution marked X, Y, and Z, and asked to arrange them in the increasing order of their pH values. The student put two drops of each solution on three strips of universal indicator paper separately. The colours shown by the three indicator strips are as follows:Which of the following gives the correct increasing order of pH values ?(1) Z (2) Y (3) X (4) Z "
