This video explains how to the calculate the hydronium ion [H3O+] and the hydroxide ion [OH-] concentration given the pH or the pOH of the solution. [7], Despite the similarity in name, sodium lactate itself is not chemically similar to lactose (milk sugar), so need not be restricted by those with lactose intolerance. As your substances are not pure, you must use 102 g of your impure lactic acid (88%), and make it react with 62.2 g of your impure (90%) potassium hydroxyde. High levels of lactate -- or, as it is sometimes called, lactic acid -- were once blamed for delayed-onset muscle soreness. Lactate is essential to the exercising process. A COD/sulfate ratio of 2.0 decreased the sulfate removal rates by 25 and 28% when ethanol and cheese whey were used as substrates.
