The molarity of the ,acid, can be calculated from the following general ,formula,: The concentration of sulphuric ,acid, is 0.106M. To make the molar concentration of the sulphuric ,acid, solution exactly equal to that of the sodium carbonate solution (0.1M), 23.6 cm 3 of the ,acid, must be diluted to 25 cm 3 , that is, 1.4 cm 3 of distilled water must be added to 23.6 cm 3 of the ,acid,.

Acid-base Chemistry. Acid-base chemistry is based on one simple reaction - the ionization of water: H2O H++ OH-. As we saw in the last lesson, this equation means that water can break apart into a hydrogen ion and a hydroxide ion. A hydrogen and a hydroxide ion can also join together to form a water molecule.
