The ADV test for foundry sands uses 50.0 grams of sand mixed with 50 ml of distilled of deionized water adjusted to pH of 7, and 50 ml of dilute hydrochloric acid. The sand, water, and acid mixture is stirred for five minutes, then the mixture is analyzed to determine how much of the dilute acid has reacted with the impurities in the sand.
1 - Making Hydrogen from Metals - IGCSE Chemistry
Any metal that reacts quickly with water is likely to react dangerously violently with acids. Most of them would explode on contact with even dilute Hydrochloric acid. Aluminium is a little less reactive, and takes a while to start reacting because it is covered with a layer of Aluminium Oxide that protects the pure metal from the acid briefly.

Gypsum crystallization and hydrochloric acid …
In this work, the crystallization of gypsum (CaSO 4 ·2H 2 O) in the temperature range of 20–60 C is investigated along with the simultaneous regeneration of HCl by the reaction of concentrated CaCl 2 solution (3–3.5 M) with H 2 SO 4 at a concentration range of 2.6–8.0 M. Fast addition of H 2 SO 4 proved counter productive as it yielded a gel-like fine crystal suspension.
