While other metal/acid coinations react in the same way, recovering the salt by crystallisation (in Lesson 2) may not be as successful as it is using zinc and sulfuric acid. Dilute hydrochloric acid, HCl(aq) – see CLEAPSS Hazcard HC047a and CLEAPSS Recipe Book RB043.
Hydrochloric acid - Newikis
Gastric acid is one of the main secretions of the stomach. It consists mainly of hydrochloric acid and acidifies the stomach content to a pH of 1 to 2. Chloride (Cl −) and hydrogen (H +) ions are secreted separately in the stomach fundus region at the top of the stomach by parietal cells of the gastric mucosa into a secretory network called canaliculi before it enters the stomach lumen.
Hypochlorite vs Chloride - What''s the difference? | WikiDiff
In context|chemistry|lang=en terms the difference between hypochlorite and chloride is that hypochlorite is (chemistry) any salt of hypochlorous acid; used as a bleach while chloride is (chemistry) any salt of hydrochloric acid, such as sodium chloride, or any binary compound of chlorine and another element or radical.

Tin reacts with strong acid but with weaker acid it does not
Hydrochloric acid → Tin (II) chloride + Hydrogen Sn + 2HCl → SnCl 2 + H 2 Tin reacts with dilute acids slower than many other metals and heat is often required to speed up the reaction. This property means tin can be used as a protective coating on other
Calcium chloride - Wikipedia
Calcium chloride is an inorganic compound, a salt with the chemical formula CaCl 2. It is a white coloured crystalline solid at room temperature, and it is highly soluble in water. It can be created by neutralising hydrochloric acid with calcium hydroxide.
