The ka of acetic acid (hc2h3o2) is 1.8 ⋅ 10-5. what is the ph at 25.0 °c of an aqueous solution that is 0.100 m in acetic acid? the ka of acetic acid (hc2h3o2) is 1.8 10-5. what is the ph at 25.0 °c of an aqueous solution that is 0.100 m in acetic acid? +2.87 -2.87 -11.13 +6.61 +11.13

2.872.

Explanation:

∴ [H⁺] = √(Ka.C) = √(1.8 x 10⁻⁵)(0.1 M) = 1.342 x 10⁻³.

∵ pH = - log[H⁺].

∴ pH = - log(1.342 x 10⁻³) = 2.872.

frequency, z, and the collision density, z, in carbon dioxide (co2), r 180 pm at 30 °c and 120 kpa

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.
