1.	The pH of ten solution is defined as the negative logarithm of the concentration of hydrogen ions which is contains. pH of 0.365 gL–1 HCl solution will be (a) 1 (b) 2 (c) 3 (d) 0.1
Answer» Correct Option (b) 2 Explanation: Molar Mass of HCl = 36.5 Concentration of HCl = 0.365/36.5 = 1 x 10^-2 molL^-1 HCl is a strong acid pH = –log[H⁺] = –log 10^–2 = –1 x –2 = 2

The pH of ten solution is defined as the negative logarithm of the concentration of hydrogen ions which is contains. pH of 0.365 gL–1 HCl solution will be (a) 1 (b) 2 (c) 3 (d) 0.1

Answer»

Correct Option (b) 2

Explanation:

Molar Mass of HCl = 36.5

Concentration of HCl = 0.365/36.5 = 1 x 10^-2 molL^-1

HCl is a strong acid

pH = –log[H⁺]

= –log 10^–2

= –1 x –2 = 2
