Why lead is not used for the preparation of hydrogen from dilute HCL or dilute sulphuric?
Lead is not reactive enough to displace hydrogen from dilute HCl or dilute sulfuric acid. The reduction potential of lead is lower than that of hydrogen, so it cannot effectively displace hydrogen in these reactions. Other metals like zinc or aluminum are used instead due to their higher reactivity and ability to displace hydrogen.

Why is nitric acid in the dilute form not used in the laboratory preparation of hydrogen from metals?
It is because nitric acid is a strong oxidising agent (because it decomposes to yield nascent oxygen as:2HNO3 →2NO2 + H2O + [O])and it oxidises the hydrogen formed to water.Only 1% dilute and cold nitric acid reacts with magnesium and manganese to liberate Hydrogen gas.
Why lead is not used for preparation of hydrogen?
Lead is not used for the preparation of hydrogen because it is not reactive enough to displace hydrogen from water or acids. Other metals like zinc or aluminum are commonly used because they react more readily with acids or water to produce hydrogen gas. Lead's lack of reactivity makes it unsuitable for this purpose.
Why concentrated sulphuric acid should not be used while preparing hydrogen gas in laboratory?
Concentrated sulfuric acid is not recommended for preparing hydrogen gas in the laboratory because it reacts violently with water, producing a lot of heat and potentially splashing acid. This can be hazardous and may lead to injury. It's safer to use dilute acid for this purpose.
Does Pb react with dilute H2SO4?
In theory, lead should react with dilute sulfuric acid, to give lead(II) sulfate and hydrogen. In practice the reaction is very slow, because lead sulfate is insoluble in water and quickly clogs up the lead surface, and because lead is relatively unreactive.
What happens when you mix nickel and dilute sulphuric acid together?
Oh, dude, when you mix nickel and dilute sulphuric acid, you get nickel sulfate and hydrogen gas. It's like a chemistry party where the nickel and acid mingle and create some new compounds. Just make sure to do it in a well-ventilated area because nobody wants a hydrogen gas surprise party.
What does lead sulphuric acid make?
Lead reacts very slowly with dilute sulphuric acid to give lead sulphate and hydrogen gas.Pb(s) + H2SO4 (aq) -> PbSO4(aq) + H2(g)
The electrolyte used in lead storage battery is dilute?
Sulphuric acid
What do automobile batteries contain?
Common automobile batteries are Lead/acid (dilute sulphuric acid) batteries.
What happens when lead is reacting with dilute acid to form hydrogen?
Ionization

What is the reaction between lead and dilute nitric acid?
The reaction between lead and dilute nitric acid produces lead(II) nitrate, nitrogen dioxide gas, and water. The balanced chemical equation is: 3Pb + 8HNO3 -> 3Pb(NO3)2 + 2NO2 + 4H2O
Why do acids liberate hydrogen gas only in dilute form when they react with metals?
Hydrogen gas is always created when metals mix with acids because it is the first element and it is always created in a chemical reaction. hope i helped ya! You are assuming that all acids have hydrogen ions to donate. This is not the most rigorous definition for an acid but for this question it will do. for example some acids are H2SO4, HCL, HF, H2CO3 What in effect happens is that the neutral metal and the ionic hydrogen trade states. The metal becomes ionic and the hydrogen become elemental (I don't want to say metallic for hydrogen even if the term does fit in this context.) Ca(s) + H2SO4 -> CaSO4 +H2(g)
Why cannot the dilute solution of hydrogen peroxide be concentrated by heating strongly?
Heating a dilute solution of hydrogen peroxide strongly can lead to rapid decomposition of the hydrogen peroxide into water and oxygen gas. This decomposition reaction is exothermic and can become uncontrollable, resulting in a dangerous buildup of pressure and potential explosion.
