22. Arrhenius defined an acid as hydrogen containing and able to form hydrogen ions in water. - True (T)
To understand this statement, we need to know what Arrhenius defined as an acid. Arrhenius defined an acid as a substance that contains hydrogen atoms and is able to release hydrogen ions (H+) when dissolved in water. This definition is based on the concept of ionization in aqueous solutions.
23. A strong acid does not have to be a strong electrolyte. - False (F)
To evaluate this statement, we need to understand the definitions of a strong acid and a strong electrolyte. A strong acid is a substance that completely ionizes in water, producing a high concentration of hydrogen ions (H+). On the other hand, a strong electrolyte is a substance that dissociates completely into ions when dissolved in water, leading to a high electrical conductivity.
Since a strong acid is a type of strong electrolyte, it means that strong acids are always strong electrolytes. Therefore, the statement "A strong acid does not have to be a strong electrolyte" is false.
31. Bases generate (OH-) ions. - True (T)
This statement is true. Bases are substances that can accept protons (H+) and generate hydroxide ions (OH-) when dissolved in water. The ability of bases to produce hydroxide ions is what allows them to neutralize acids.
32. A neutralization reaction forms water from hydronium and hydroxide ions. - False (F)
In a neutralization reaction, an acid reacts with a base to form a salt and water. The reaction involves the transfer of a proton (H+) from the acid to the base. Water is indeed formed in the neutralization reaction, but not from hydronium (H3O+) and hydroxide (OH-) ions directly. Hydronium and hydroxide ions are not typically present as reactants. They are formed in the reaction as intermediates or during the dissociation of acid and base in water.
33. Acidic anhydrides are very often nonmetal oxides. - True (T)
Acidic anhydrides are compounds that can react with water to form acids. These compounds are often nonmetal oxides. Nonmetal oxides tend to have acidic properties because they can react with water to produce acids. Common examples of acidic anhydrides include sulfur dioxide (SO2), carbon dioxide (CO2), and nitrogen dioxide (NO2).
35. Acids react with all metals. - True (T)
Acids have the ability to react with metals, typically producing hydrogen gas (H2) and a salt. This reaction occurs because acids can donate protons (H+) to metal atoms, leading to the formation of metal ions and hydrogen gas. However, the reactivity of acids with metals can vary. Some acids may react with certain metals more readily than others, depending on factors such as the metal's reactivity and the concentration and nature of the acid being used.
