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.
NaCl(Table Salt) is soluble in water. Reaction: NaCl(solid) + H2O -> Na+(aqueous) + Cl-(aqueous) + H2O. Explanation: On addition to water the Na+ section of NaCl is attracted to the oxygen side of the water molecules, while the Cl- side is attracted to the hydrogens' side of the water molecule.
