The unit cell of nickel arsenide is shown here.
(a) What type of lattice does this crystal possess?
(b) What is the empirical formula?
Step 1 of 5) A strong acid completely transfers its protons to water, leaving essentially no undissociated molecules in solution. (Section 4.3) Its conjugate base has a negligible tendency to accept protons in aqueous solution. (The conjugate base of a strong acid shows negligible basicity.) 2. A weak acid only partially dissociates in aqueous solution and therefore exists in the solution as a mixture of the undissociated acid and its conjugate base. The conjugate base of a weak acid shows a slight ability to remove protons from water. (The conjugate base of a weak acid is a weak base.) 3. A substance with negligible acidity contains hydrogen but does not demonstrate any acidic behavior in water. Its conjugate base is a strong base, reacting completely with water, to form OH- ions. (The conjugate base of a substance with negligible acidity is a strong base.)The ions H3O+1aq2 and OH- 1aq2 are, respectively, the strongest possible acid and strongest possible base that can exist at equilibrium in aqueous solution. Stronger acids react with water to produce H3O+1aq2 ions, and stronger bases react with water to produce OH- 1aq2 ions, a phenomenon known as the leveling effect.
