Hydrogen Ion Concentration | MCQs
پی ایچ ______ کے باہمی تعاون کا لوگرتھم ہے؟
-
A. Phosphorus ion concentration
-
B. None of these
-
C. Phosphine ion concentration
-
D. Hydrogen ion concentration
Explanation
- pH is defined as the negative logarithm of the hydrogen ion concentration in a solution.
- It is a measure of the acidity or basicity of a solution.
-
A. 1.802 × 10²⁴
-
B. 1.204 × 10²³
-
C. 1.204 × 10²⁴
-
D. None of these
Explanation
- Moles of H₂SO₄ = mass / molar mass = 9.8 g / 98 g/mol = 0.1 mol.
- Each H₂SO₄ molecule releases 2 H⁺ ions.
- So total H⁺ ions = 0.1 mol × 2 × 6.022 × 10²³ = 1.204 × 10²⁴ ions.
