WebWhat is Ethanoic Acid? Ethanoic acid (CH 3 COOH) belongs to the group of carboxylic acids and is commonly called as acetic acid. It is slightly heavier than water with a density of 1.05 g/cm 3. After adding 5-8% of acetic acid … WebApr 26, 2024 · The pH scale measures how acidic or alkaline a substance is. It runs from 0 to 14, with a pH of 7 being neutral, a pH lower than 7 being acidic and a pH higher than 7 being alkaline. The scale is logarithmic, meaning each whole pH value below 7 is ten times more acidic than the next higher value.
