What is potential Hydrogen in terms of ionic equilibria?​

Potential Hydrogen is the negative logarithm of molar hydrogen concentration.

Explanation:

potential Hydrogen has its abbreviation as pH

altitude, density, pressure

air gets less dense the higher the altitude and also the air pressure is less as altitude rises.

in the given question, the partial pressure is calculated by using the ideal gas equation, that is, pv = nrt

here, p is pressure, v is volume = 25 l, n is number of moles = 0.0104 moles, r is gas constant = -0.0821 l.atm / mol.k

t is temperature = 273 k

p = nrt / v

p = (0.0104 mol × 0.0821 l.atm / mol.k × 273 k) / 25 l

= 0.0093 atm
