How is the formula for alkali power consumption derived?

The electrochemical equivalent of alkali is 1.492 g·A-1·h-1. This post was last edited by wenyuyu on 2009-4-22 12:36.] # hcbbs
W = QU/1000η = 1,000,000U/1000Kη; this represents the electrical energy actually consumed to produce 1 ton of NaOH, expressed in kilowatt-hours. The second equality uses the formula m = KQ, where m is the mass of NaOH in grams and Q is the electric charge in Ah. Multiplying by 1000, or 1,000,000, is used to convert units
