Question

103. A substance is dissolved in water and
the only positive ions in the solution are
H1+ ions. This substance is
1) KOH
2) NaH
3) H2SO4
4) NH

104. Which is true about a solution that is
acidic?
1) [Hl] equals zero.
2) [OH!] equals [H].
3) [Hlt] is less than [OH!].
4) [H\t] is greater than [OH'].​

Answer 1

Answer:

103.H2SO4

104.[H+] is more than [OH-]

Explanation:

103.Solutions of acids and bases produce some ions that can carry electric current, so they are said to be electrolytes. Acids contain at least one hydrogen atom that can be removed when the acid is dissolved in water. An acid is a substance that produces hydrogen ions in a water solution. When an acid dissolves in water, hydrogen ions interact with water to form hydronium ions. The strength of an acid or base depends on how many acid or base particles dissociate into ions in water. When a strong acid dissolves in water all molecules ionize into ions. When a weak acid dissolves in water a small fraction dissolve in water.

104.[H+] is more than [OH-]

Explanation:- An acidic solution is one in which there is a high concentration of Hydrogen ions i.e. H+. Thus option four is correct. [OH-] is higher in case of basic solution.
