Isotonically → It is formed from "iso-" (meaning equal) and "tonos" (from Greek, meaning tension or tone) and the suffix "-ic" (meaning pertaining to). The word describes a condition pertaining to equal tension or tone, often used in the context of solutions having the same osmotic pressure as another solution.
Think of 'equal' ('iso-') tension or 'tone' ('tonos') when you hear 'isotonically', which refers to solutions that maintain equal pressure.
