    In general, for an acid AH n at concentration c 1 reacting with a base B(OH) m at concentration c 2 the volumes are related by: n v 1 c 1 = m v 2 c 2. An example of a base being neutralized by an acid is as follows. Ba(OH) 2 + 2 H + → Ba 2+ + 2 H 2 O. The same equation relating the concentrations of acid and base applies.

    Crystallization separates a product from a liquid feed stream, often in extremely pure form, by cooling the feed stream or adding precipitants that lower the solubility of the desired product so that it forms crystals. The pure solid crystals are then separated from the remaining liquor by filtration or centrifugation.

    Heptanal reacts with benzaldehyde in a Knoevenagel reaction under basic catalysis with high yield and selectivity (> 90%) to jasminaldehyde, [11] [2] which is mostly used in fragrances for its jasmine-like aroma as a cis/trans isomer mixture. [12] A by-product of the given reaction is the unpleasant rancid smelling (Z)-2-pentyl-2-nonenal. [13]
