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.
What else can I help you with?
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 calcium is not used in the lab preparation of hydrogen?
Calcium is not used in the lab preparation of hydrogen because it reacts with water to form calcium hydroxide and hydrogen gas, making it an inefficient method for producing pure hydrogen. Other methods such as using metals like zinc or aluminum are preferred for lab preparation of hydrogen as they do not form unwanted byproducts.
Why is HNO3 not used in preparation of hydrogen gas?
HNO3 is not used in the preparation of hydrogen gas because it is a strong oxidizing agent. When HNO3 reacts with a metal to produce hydrogen gas, it tends to oxidize the hydrogen gas produced back to water, making the reaction inefficient for hydrogen gas production.
Why potassium is not used in preparation of hydrogen?
Potassium is not used in the preparation of hydrogen because it is a highly reactive metal that reacts vigorously with water to form potassium hydroxide and hydrogen gas. This reaction can be dangerous due to the high reactivity of potassium, making it unsuitable for the controlled generation of hydrogen gas. Sodium is often used instead as it reacts less violently with water.
What is the word equation for the preparation of hydrogen?
The word equation for the preparation of hydrogen gas is: metal + acid → salt + hydrogen gas. For example, when hydrochloric acid reacts with zinc, it produces zinc chloride salt and hydrogen gas.

Is Hydrogen the most common resource?
i think hydrogen is some what common we just don't know it. Hydrogen is used as a fuel. It is used for the manufacturing of fertilizers. It is used in the preparation of vegetable ghee. It is used as rocket fuel. It is used in the preparation of ammonia (NH3) and methanol (CH3OH). It is used in the preparation of oxy-hydrogen flame which is used in welding due to production of high temperature. It is used in filling weather balloons. It is used to prepare tungsten filament. It is used to prepare low temperature in liquid state.

How many hydrogen are in lead?
there is no Hydrogen in Lead because Lead is a chemical element just like Hydrogen.
What does black-leaded mean?
Black lead is a graphie preparation used to clean and preserve cast iron stoves and fireplaces. Black-leaded is the term used for an article that has had the preparation applied.
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.
What is bleached?
Bleach is a chemical, such as sodium hypochlorite or hydrogen peroxide, or a preparation of such a material, used for disinfecting.
Food grade hydrogen peroxide?
Food grade hydrogen peroxide refers to a highly diluted form of hydrogen peroxide that is safe for use in food preparation and consumption. It is typically 35% hydrogen peroxide diluted to 3% or less with water to ensure safety. It is used as a natural disinfectant and for various other purposes in food processing and preparation.
Why nitric acid is not used in lab preparation hydrogen?
Nitric acid is a strong oxidizing agent that can react violently with reducing agents such as hydrogen, leading to potential explosions. This makes it unsafe to use nitric acid in the lab for the preparation of hydrogen gas. Preferred methods for generating hydrogen gas typically involve non-oxidizing acids like hydrochloric acid reacting with a metal like zinc.
