3Au + 2HCl → 3H2 + 2AuCl3 | Phương Trình Phản Ứng Hóa Học

Au | gold | solid + HCl | hydrogen chloride | solid = H2 | hydrogen | solid + AuCl3 | tetrachloroauric acid | solid | Temperature: temperature, Other Condition excess chlorine

Detailed information about the equation

Reaction conditions when applied Au + HCl

  • Catalyst: not available
  • Temperature: normal
  • Pressure: normal
  • Other conditions: not available

Reaction process Au + HCl

Process: Place the Au sample in a test-tube containing the dilute HCl solution, and shake gently.

Note: The reducing potential of gold is higher than hydrogen (in other words, Au is behind H2 in the metal reactivity series), so Au does not react with a HCl solution.

The result of the reaction Au + HCl

The phenomenon: This reaction does not occur
