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 else can I help you with?
What salt is formed when aluminium reacts with potassium hydroxide during preparation of hydrogen from alkali's?
Potassium aluminate is the salt formed when aluminum reacts with potassium hydroxide in the preparation of hydrogen from alkalis. This reaction produces hydrogen gas along with the formation of potassium aluminate as a byproduct.
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.
What is another name for potassium hydrogen carbonate?
Another name for potassium hydrogen carbonate is potassium bicarbonate.
What is K2HPO4 as an ionic compound?
K2HPO4 is an ionic compound known as dipotassium hydrogen phosphate. It consists of potassium ions (K+) and hydrogen phosphate ions (HPO4^2-). The potassium ion has a +1 charge, while the hydrogen phosphate ion has a -2 charge.
Can potassium chloride be prepared from zinc and hydrogen chloride?
No, reacting zinc with hydrogen chloride will yield zinc chloride and hydrogen gas. Potassium chloride can be prepared by reacting potassium with hydrogen chloride or (more safely) potassium hydroxide with hydrogen chloride.
What salt is formed when aluminium reacts with potassium hydroxide during preparation of hydrogen from alkali's?
Potassium aluminate is the salt formed when aluminum reacts with potassium hydroxide in the preparation of hydrogen from alkalis. This reaction produces hydrogen gas along with the formation of potassium aluminate as a byproduct.
Why are soaps basic?
Sodium and potassium hydroxides are used in the preparation of soaps.

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.

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 is the addition of concentrated sulfuric acid to solid potassium iodide unsuitable for the preparation of hydrogen iodide?
The reaction between concentrated sulfuric acid and solid potassium iodide does not produce hydrogen iodide. Instead, it generates sulfur dioxide gas, potassium sulfate, and iodine. Therefore, this reaction is unsuitable for obtaining hydrogen iodide.
Potassium iodide is used in what?
- potassium iodide is added to table salt as a source of iodine- potassium iodide is a food supplement during a nuclear accident in a nuclear reactor- for the preparation of AgI
Is potassium hydrogen tartrate a solid liquid or gas at room temperature?
Potassium hydrogen tartrate is a solid at room temperature. It is commonly known as cream of tartar and is used in baking and cooking.
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.
