Ball 111 and ball 222 follow the paths shown. This is in contrast to acids capable of donating more than one proton or hydrogen, which are called polyprotic acids. When the conjugate acid and the conjugate base are of unequal strengths, the solution can be either acidic or basic, depending on the relative strengths of the two conjugates. Theoretically and literature values state that $\ce{CaCl2}$ is acidic, but my empirical evidence shows that it is basic. These lone pairs of electrons are used by Lewis acids to complete their orbitals. D. basic, because of the ionization of CH 3 NH 2. The concentration of C6H5CH2COOH [C6H5CH2COOH] =.
