The hydrogen gas bubbling into one molar solution of HCl has a pressure of
Correct answer: D. 1 atm
- A. 2 atm
- B. 780 mmHg
- C. 19 Psi
- D. 1 atm
Explanation
When hydrogen gas bubbles into a one molar solution of HCl, it is usually assumed to be at standard conditions unless otherwise specified. Standard atmospheric pressure is 1 atm. Therefore, Option D is correct. Option A suggests a pressure higher than atmospheric, which is not standard for gases in such scenarios. Option B, at 780 mmHg, is close but not exactly standard atmospheric pressure. Option C, at 19 Psi, exceeds standard atmospheric pressure of approximately 14.7 Psi (1 atm).

About Electrochemistry
Electrochemistry describes electron transfer through oxidation and reduction, identifies oxidizing and reducing agents, and applies oxidation numbers to balance redox equations. It also covers electrode potential and the standard hydrogen electrode, which provides the reference for comparing the reduction tendencies of other electrodes.
