| Direction: Assertion- Reason type each of these contains two statements: Statements I (Assertion), Statement II (Reason). Each of these questions also has four alternative choices. Only one of which is correct. You have to select the correct choices from the codes [a], [b], [c] and [d] given below: |
| Statement I: pH of 10 M HCI aqueous solution is less than 1. |
| Statement II: pH is negative logarithm of \[{{\text{H}}^{+}}\]Concentration. |
A) Statements is true; Statement II is true; Statements II is not the correct explanation for Statements I.
B) Statement I is true; Statement II is false.
C) Statement I is false; Statement II is true.
D) Statement I is true; Statement II is true; Statement II is the correct explanation for Statement I.
Correct Answer: A
Solution :
Theoretically the pH should be negative. But practically it is not possible because effective concentration of \[{{H}_{3}}{{O}^{+}}\]ions will not be equal to 10 M in such a concentrated solution. Hence, pH is approximately zero.
