A scientist makes a boric acid (H3BO3) solution by dissolving 22.5 g of H3BO3 in water to make 750.0 mL of solution. Calculate the number of moles of H3BO3 present:

As the weak acid (HA) is titrated with a strong base (OH-), the neutralization reaction is: HA + OH - → A - + H2O. As the neutralization occurs, [HA] decreases and [A-] increases, allowing the solution to act as a buffer. Suppose 0.0015 mol HA and 0.

Atoms of elements on the left side of the periodic table have lower ionization energies than elements on the right. Using your knowledge of ions you could infer that ionization energy refers to the energy needed for an atom to- A. lose electrons. B.
