WebThe pH scale is often said to range from 0 to 14, and most solutions do fall within this range, although it’s possible to get a pH below 0 or above 14. Anything below 7.0 is acidic, and anything above 7.0 is alkaline, or basic. … WebAnswer (1 of 6): What weight of NaOH is required to prepare 200ml solution of ph=12? 1. Since pH + pOH = 14 and pH = 12. Then pOH = 2 2. For pOH 2, OH = 1 x 10^-2 mol/L 3. …
WebSep 22, 2024 · The concentration of acetic acid in vinegar may be expressed as a molarity (in mol/L): (11.1) Molarity = Moles of Acetic Acid Volume of Vinegar (in L) or as a mass percent. (11.2) Mass % = ( Mass of Acetic Acid Mass of Vinegar) × 100 %. In this experiment, a technique known as a titration will be used to determine the concentration of acetic ... WebWhat is the equation used for Molarity Conversion? The following equation is used for calculating acid and base molarity where the concentration is given in wt %: [ (% × d) / MW] × 10 = Molarity Where: % = Weight %; d = Density (or specific gravity); MW = Molecular Weight (or Formula Weight).
