How do you know if an acid is triprotic

WebJun 18, 2024 · Since you know that 0.0008332 moles of acid have a mass of 0.16 g, you can say that the molar mass of the acid is equal to. molar mass = 0.16 g 0.0008332 moles = 192 g mol−1. The relative molecular mass of the acid, Ar, is a unitless quantity calculated by dividing the molar mass by 1 g mol−1. Ar = 192g mol−1 1g mol−1 = 190 −− −. WebExample: Consider the process by which we would calculate the H 3 O +, OAc -, and HOAc concentrations at equilibrium in an 0.10 M solution of acetic acid in water. We start this calculation by building a representation of what we know about the reaction. HOAc ( aq) +. H 2 O ( l) H 3 O + ( aq) +. OAc - ( aq) Ka = 1.8 x 10 -5.

Question #eed26 Socratic

WebDetermine if an acid is monoprotic, diprotic, or triprotic given the chemical formula. Monoprotic We can classify acids by the number of protons per molecule that they can give up in a reaction. Acids such as HCl, HNO 3, and HCN that contain one ionizable hydrogen atom in each molecule are called monoprotic acids. Their reactions with water are: WebTo find the normality of the citric acid solution, we need to know the number of equivalents of citric acid in the solution. Citric acid is a triprotic acid, which means that each molecule can donate three hydrogen ions (protons) in an acid-base reaction. Therefore, the number of equivalents of citric acid is three times the number of moles of ...

WebWe can construct an acid dissociation expression for strong acids and calculate their Ka and pKa values. These values indicate that the products of a strong acid reaction are heavily favored compared to the reactants. So very large numbers for Ka and negative values for pKa for strong acids. http://barbara.cm.utexas.edu/courses/ch302/files/ln16s09polyproticacids.pdf

WebThe concentration of an acid solution can be determined by titration with a strong base. First, calculate the number of moles of strong base required to reach the equivalence point of the titration. Then, using the mole ratio from the balanced neutralization equation, convert from moles of strong base to moles of acid. WebH-O-Y acids (Y is usually a Group 17 atom) exhibit greater dissociation if the Y atom is more electronegative. This is because the electronegative Y will pull electrons towards itself …
