Tin Reacting with Hydrochloric Acid
Sn + 2HCl → SnCl2 + H2
ภาพรวม
Tin reacts slowly with hydrochloric acid to produce tin(II) chloride (stannous chloride) and hydrogen gas. Tin is relatively low in the activity series, so the reaction is sluggish at room temperature but proceeds at a reasonable rate when heated.

ตัวอย่างในชีวิตประจำวัน
Tin cans (steel coated with tin) are resistant to food acids partly because tin reacts slowly with acids, protecting the steel underneath.
ความสำคัญทางอุตสาหกรรม
Tin(II) chloride is used as a reducing agent in analytical chemistry, in tin electroplating, and as a sensitizer in silvering mirrors.
