How will you prepare hydrogen from zinc and dilute acid.

1 answer:

7 0

Hydrogen is basically prepared by action of dilute acids On metals.
Dilute Hydro chloric acid is added To zinc granules. The hydrogen produced is then passed through anhydrous calcium chloride or concentrated sulphuric acid. The hydrogen collected by upward delivery because it is lighter than air. If the reaction is too slow Copper (II) Sulphate solution can be added to speed up the solution.
Zn (s)+ 2HCl (aq)———ZnCl2 (aq)+ H2(g).

Describe the term molarity as it relates to an acid or base.

Sidana [21]

Molarity is expressed as the number of moles of solute per volume of the solution. For example, we are given a solution of 2M NaOH this describes a solution that has 2 moles of NaOH per 1 L volume of the solution. Acids and bases can be measured through the concentrations of H+ and OH- ions in units of molarity. Hope this helps.
