IPA: //pɜːrˈbɔːreɪt//
KK: /pɜrˈbɔːreɪt/
A type of salt that is made from a combination of borate and hydrogen peroxide.
The chemist used perborate in the experiment to create a bleaching agent.
Perborate → It is formed from "per-" (meaning through or thoroughly) and "borate" (derived from "boron" which refers to the chemical element). The word "perborate" means to thoroughly treat or combine with boron, often used in the context of chemical compounds that contain boron.
Think of 'through' ('per-') and 'boron' when you remember that 'perborate' refers to a compound that thoroughly involves boron.
