tract as in the dolichosaurs, are also noticeable in the aigialosaurs, though to a weaker extent; but what the aigialosaurs always lack is the deflection or folding-over of the tail which is common in the dolichosaurs.
Sodium chloride is an ionic compound that is produced by the bonding of sodium cations to chloride anions. This salt dissolves readily in water and forms crystals when in solid form. Uses of sodium chloride can be both commercial and biological.
The picture above shows the colour arising from adding common salt (NaCl) to a burning mixture of potassium chlorate and sucrose. The chemistry of sodium is dominated by electron loss to form Na + . Cartoon by Nick D Kim ([Science and Ink] , used by permission).
