Question
On adding dilute sulphuric acid to a test tube containing a metal ‘X’, a colourless gas isproduced when a burning match stick is brought near it. Which of the following correctlyrepresents metal ‘X’?
Solution
The question is asking about a reaction between a metal and dilute sulphuric acid that produces a colorless gas which can be ignited. This is a common description of the reaction between a metal and an acid, which often produces hydrogen gas. Hydrogen gas is colorless and can be ignited, so it fits the description given in the question.
The metals that react with acids to produce hydrogen gas are typically those that are more reactive than hydrogen in the reactivity series of metals. This includes metals like magnesium, zinc, and iron, among others.
So, without more specific information, it's not possible to definitively identify metal 'X'. However, based on the information given, we can say that metal 'X' is likely a metal that is more reactive than hydrogen in the reactivity series of metals.
