On the other hand, nitric acid produces both #H^+# and #NO_3^-# ions, which taken together do make a strong oxidizing agent. with Nitric Acid giving off Hydrogen and NitroDioxide Gas. Depending on the reactivity,some metals react violently with dilute acids,some metals react rapidly with dilute acids,some metals react with dilute acids only on heating. The general equation that describes the chemical reaction between an acid and metal is metal + acid = salt + hydrogen gas. The metals like Cu,Au,Ag are less reactive than hydrogen.They do not displace hydrogen from dilute acids. Thus, nitric acid will dissolve silver, but not gold. Metals react with acid to give salt and hydrogen gas. Recall that acids react with some metals and with carbonates, and write equations predicting products from given reactants. It is because Aluminium is a reactive metal It reacts with acids contained in food to form toxic salts Reaction of less reactive metals with Acids Less reactive metals do not react with dilute acids Hence they are also called brittle. Exception: Mercury. Only the less reactive metals like copper,silver and gold do not react with dilute acids. AQA Combined science: Trilogy. Beryllium is a good example. Which metals do not react with acid to produce hydrogen. produce Hydrogen Gas. Metals are ductile, i.e., they can be drawn into wires. All metals which are more active than lead react with dilute hydrochloric acid or dilute sulfuric acid##. However, some metals like Al, Pb, Zn react with strong bases like NaOH to form complex salts and hydrogen gas. Hydrogen gas forms as the metals react with the acid to form salts. All metals will react with FluoroAntimonic Acid, Xenic Acid, or The right answer must be copper, but why doesn't copper react with hydrochloric acid while the other metals do? We checked the reactivity of various metals with oxygen, water and acids. Metals are sonorous, i.e., they produce ringing sound when struck.
