The imidazolium ion has a pka = 7.0. imidazolium buffers can be prepared for ph values of

Buffer is a solution containing a weak acid or a base and its salt. The solution resists the change in pH with addition of acid or alkali. This is known as the buffer capacity. The buffer capacity is the most effective only within a certain pH range which is usually pH = pKa +/- 1

The imidazolium ion has a pKa = 7. Therefore, the most effective pH range is 6 to 8.

c)red bank

explanation:

red bank is a borough in monmouth county, new jersey, incorporated in 1908 and located on the navesink river, the area's original transportation route to the ocean and other ports.

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
