Why concentrated hydrochloric acid is not used to prepare hydrogen gas in laboratory?
Concentrated hydrochloric acid (HCl) is not typically used to prepare hydrogen gas in the laboratory because it can react violently with some metals, leading to the release of hazardous hydrogen gas and potentially causing explosions. Dilute hydrochloric acid is safer to use for this purpose as it produces hydrogen gas more slowly and can be better controlled.

How do you prepare HCL solution in Laboratory?
Hydrochloric acid is prepared by dissolving hydrogen chloride gas in water. Hydrogen chloride is a covalent compound, but when dissolved in water it ionizes to form hydrogen ions and chloride ions as follows: By Kuldeep K. bansal INDIA
How do prepare 0.01M methanolic hydrochloric?
To prepare a 0.01M methanolic hydrochloric acid solution, mix the appropriate volume of concentrated hydrochloric acid with methanol to achieve the desired concentration. For example, to make 1L of 0.01M solution, dilute 8.9mL of concentrated hydrochloric acid (37%) with methanol and then dilute to the final volume with methanol. Make sure to handle concentrated hydrochloric acid with caution and wear appropriate protective equipment.
How can you prepare 0.01n hydrochloric acid?
To prepare 0.01 N hydrochloric acid, you would need to dilute concentrated hydrochloric acid (typically 37% concentration) with distilled water in a volumetric flask. Calculate the volume of concentrated acid needed based on the desired final volume and concentration of the solution. Be sure to wear appropriate safety gear and handle the concentrated acid with caution.
Why copper is not used to prepare hydrogen in the laboratory?
Copper is not typically used to prepare hydrogen in the laboratory because it is not reactive enough to displace hydrogen from water or acids. Other metals like zinc or aluminum are more commonly used for this purpose as they have a higher reactivity with water or acids.
How do you prepare 0.4 M hydrochloric acid?
To prepare 0.4 M hydrochloric acid solution, you can dilute concentrated hydrochloric acid (typically around 12 M) with distilled water in a volumetric flask. Calculate the volume of concentrated acid needed using the formula C1V1 = C2V2, where C1 is the concentration of your concentrated acid, V1 is the volume of concentrated acid needed, C2 is the desired final concentration (0.4 M), and V2 is the final volume of the solution. Always add acid to water slowly and with stirring to avoid splattering and potential hazards.

Why is pure zinc not used to prepare hydrogen gas?
Pure zinc is not used to prepare hydrogen gas because it does not react with water to produce hydrogen gas. Instead, zinc reacts with acids like hydrochloric acid to form zinc chloride and release hydrogen gas. This reaction is utilized in the laboratory to produce hydrogen gas.

How hydrogen can be prepare at room temperature?
React hydrochloric acid with a metal such as Mg 2HCl+Mg-->MgCl2+H2
How do you prepare 1000 ml 1 M hydrochloric acid solution from concentrated hydrochloric acid?
To prepare 1000 mL of 1 M HCl solution from concentrated HCl (typically 37% w/w), you would need to dilute 88 mL of concentrated HCl with distilled water to reach the 1000 mL mark. This is because the concentrated HCl is about 12 M. Be sure to add the acid slowly to water while stirring, and always handle concentrated acids with caution due to their corrosive nature.
How much water must be mixed with concentrated hydrochloric acid to prapare 50cm3 of 6m hcl solution?
To prepare a 6M hydrochloric acid solution, you would need to dilute the concentrated hydrochloric acid. The volume of concentrated acid required would depend on its concentration. However, assuming the concentrated acid is 12M, you would need to mix 25 cm3 of the concentrated acid with 25 cm3 of water to prepare 50 cm3 of 6M HCl solution using the formula M1V1 = M2V2.
How do you prepare hydrogen in a laboratory?
