Evening Republican, Volume 15, Number 174, Rensselaer, Jasper County, 25 July 1911 — Lifting Power of Gas. [ARTICLE]

Lifting Power of Gas.

One thousand cubic feet of coal gas will life 35 pounds weight. Hydrogen gas 4 has greater lifting power, 1,000 qubic feet of it lifting from 60 to 70 pounds. One of the cheapest ways to make hydrogen gas is to act on zinc with sudphuric acid. Sulphuric acid is, chemically speaking, sulphate of hydrogen, and when it and zinc are brought in contact the zinc takes the place of the hydrogen, which is then liberated, sulphate of zinc being formed as the result of the decomposition.
