Etymology

Chromate comes from the Greek root chrom-, from chroma meaning 'color', and it shares this root with familiar words like chrome and monochrome. Many chromate salts are bright yellow or orange, so the name shows their strong 'color' and explains why we call these colored chromium salts 'chromates'.
