Sodium Hydroxide="Washing Soda", no?
During the American Civil War, Thaddeus Lowe had gas generators that used sulphuric acid to dissolve iron filings, thus producing H2 gas and Ferric (ferrous?) sulphate, or so my long-ago Chemistry lessons are trying to convince me.

Yep. Any Sodium Hydroxide will produce at least some gas. There are more than a dozen ways to make Hydrogen gas; Those three were just off the top of my head (scary note... there are at least as many ways to make poison gas from ordinary household chemicals too).
