Chemistry

Answer:

Lewis acid is a substance that donates a lone-pair of electrons.

Explanation:

What is said in the statement corresponds to a Lewis base, not an acid. For example, NH3 is a Lewis base, since it is capable of donating its pair of electrons. Trimethylborane (Me3B) is a Lewis acid, since it is capable of accepting a solitary pair.

Answer : The incorrect statement is, Lewis acid is a substance that donates a lone-pair of electrons.

Explanation :

According to the Arrhenius theory, an acid is a substance that ionizes in the water to give hydronium ion (H_3O^+) or hydrogen ion (H^+) and a bases is a substance that ionizes in the water to give hydroxide ion (OH^-).

According to the Bronsted Lowry concept, Bronsted Lowry-acid is a substance that donates one or more hydrogen ion in a reaction and Bronsted Lowry-base is a substance that accepts one or more hydrogen ion in a reaction.

According to the Lewis acid-base theory, an acid is a substance that accepts pairs of electrons and the a base is a substance that donates pairs of electrons.

The pH of an acid is always less than 7.

Hence, the incorrect statement is, Lewis acid is a substance that donates a lone-pair of electrons.

Refer to aqueous solutions containing 1:1 mole ratios of the following pairs of substances. Assume all concentrations are 1 M.
LekaFEV [45]

Answer:

c) HCl and NaCl

Explanation:

Since all the solutions are on a 1:1 mole ratio the comparison is straight forward.

The lowest pH will be for solution c) which has a strong acid, HCl, which ionizes 100 % and the neutral salt NaCl (which is neutral since it is derived from the reaction of the strong acid HCl and the strong base NaOH).

Solutions a) and b) are buffers of  the weak base NH₃ and its conjugate acid NH₄⁺ and weak acid H₃PO₄ and its conjugate weak base NaH₂PO₄ respectively.

Solution c) is a basic solution being a mixture of the weak base NH₃ and the strong base NaOH

Solution e) is a mixture of a weak base NH₂ and weak acid HC₂H₃O₂
