They cannot displace hydrogen from the non-metal anion. Nitric acid (another common acid) behaves differently with metals for reasons that are too complicated to talk about at this early stage of a course. The arrangement of metals in decreasing order of their reactivities is called reactivity series or activity series of metals. this is due to the fact that they are below hydrogen in the reactivity series. Platinum will not react with dilute acids. In other words, when a metal is added to dilute acids, salt and hydrogen gas are formed. Question 10 Write an equation for reaction of zinc with sulphuric acid? Question 7 What happens when zinc react with HCl? Following is the general equation for such metals. It cannot supply electrons to H + and hence, it does not displace hydrogen from dilute acids. Name the gas evolved when a metal react with dilute acid? This method is used in laboratory to produce hydrogen gas. Required fields are marked *, When a metal react with dilute nitric acid,then hydrogen gas is not evolved.Nitric acid is a strong oxidising agent.As soon as hydrogen gas is formed in reaction between metal and dilute nitric acid,the nitric acid oxidises this hydrogen to water.Nitric acid itself is reduced to nitrogen oxides such. A more active metal will react more readily with an acid than a less active metal. Non-metals do not react with dilute acids. So, as soon as hydrogen gas is formed in the reaction between a metal and dilute nitric acid, the nitric acid oxidisesthis hydrogen to water. Your email address will not be published.
