WebCopper does not react with hydrochloric acid. Let us discuss metals and their reactions with dilute acids briefly. All metals do not react with the same rate. Metals are... WebAs a result, zinc interacts with dilute hydrochloric acid HCl but copper does not. Zinc reaction with dilute hydrochloric acid: Zinc is more reactive than hydrogen, it reacts with hydrochloric acid to release hydrogen gas and hence displace it. Zinc quickly interacts with acid to form hydrogen bubbles.

Web4. In the case of copper, no bubbles are seen and the temperature also remains unchanged. This shows that copper does not react with dilute HCl. (a) 2 and 4 (b) 3 and 4 (c) Only 3 (d) 1, 2 and 4 Sol : 106. Four metals A, B, C and D are tested with water steam and dilute hydrochloric acid and its observation is listed below. Web2 years ago. Undiluted acids are very dangerous. Concentrated HCl or Concentrated H2SO4 will react VERY vigorously with the metal. The reaction with concentrated acids …
WebJan 3, 2016 · 1. Copper is an unreactive metal and doesn’t react in normal circumstances with dilute acids. However, it does react with nitric acid. Why is this? Nitric acid is an oxidizing agent and the reaction is not the usual acid + metal reaction. The products are oxides of nitrogen instead of hydrogen. WebAug 15, 2024 · These metals react with with dilute sulfuric acid just as they did with dilute hydrochloric acid; the reaction between magnesium and dilute sulfuric is familiar to many beginning chemists. Hydrogen gas is formed, along with colorless solutions of beryllium or magnesium sulfate. For example: \[ Mg + H_2SO_4 \rightarrow MgSO_4 + H_2\]
WebCopper does not react with HCl dilute reacts in the presence of air or oxygen because it gets oxidized to Cu 2+ and thus forms CuCl 2. But in case of Cu+HCl Cu 2Cl 2(ΔG>0) is … WebMar 22, 2024 · Dilute acids won’t have a capability to react with few metals due to the less activity of few meals when compared to hydrogen ions. Complete answer: - In the question it is asked to find the chemical elements which do not react with dilute acids. - Coming to the given options, option A. Copper.
