find the ph of 0 050 m sodium butanoate

03 09 2009If 3 0 g of Butanoic Acid (C3H7COOH) is dissolved in enough water to make 1 0L of solution what is the resulting pH? I'm also given the addition information that its ionization constant Ka = 1 510^–5 Since the acid only partially dissociates you have to use the Ka value but I can't seem to find a formula anywhere So if anyone could help that would be great! After heating for several minutes as shown in the diagram the pH indicator solution turned red Liquid Q could be A propanone B paraffin C propan-1-ol D propan-2-ol 15 The structure of a molecule found in olive oil can be represented as shown (a) Olive oil can be hydrolysed using sodium hydroxide solution to produce sodium salts of fatty acids Name the other product of this reaction

The pH range for efficient α− amylase usage is 6 0-6 5 although enzymes with good activity at pH 5 5-5 7 are now available Therefore mash pH should be controlled in this range from the first enzyme addition until the end of liquefaction The glucoamylase enzyme has a lower pH range (4 0-5 5) so after liquefaction the pH of the mash should be adjusted with either sulfuric acid or backset

Calculate percent dissociation of a)0 0074 M butanoic acid

Sodium butanoate is soluble in aqueous solution which means that it will dissociate completely to form sodium cations which are of no interest to you and butanoate anions You will thus be dealing with the common ion effect - because the solution already contains a significant amount of conjugate base molecules the equilibrium will be pushed to the left i e fewer acid molecules will

pH = 3 57 Your buffer contains hydrofluoric acid HF weak acid and sodium fluoride NaF the salt of its conjugate base the fluoride anion F^(-) When the sodium hydroxide solution is added assuming with no change in the total volume of the buffer you can expect the weak acid and the strong base to neutralize each other Moreover this reaction will result in the production of
