why is the pH at end point for a titration of a weak acid with a strong base is greater than 7, yet that of the titration of a strong acid with a strong base is equal to 7?
Strong acid and strong base at the end point form neutral salt and water.
Both these components are neutral and hence pH would be 7
On the other hand, weak acid react with strong base to form conjugate base at end point. Due to presence of conjugate base, pH is greater than 7
why is the pH at end point for a titration of a weak acid with a strong base is greater than 7, yet that of the titration of a strong acid with a strong base is equal to 7?
A. Match each type of titration to its pH at the equivalence point. Weak acid, strong base Strong acid, strong base Weak base, strong acid pH less than 7 pH equal to 7 pH greater than 7 B. A 56.0 mL volume of 0.25 M HBr is titrated with 0.50 M KOH. Calculate the pH after addition of 28.0 mL of KOH. C. Consider the titration of 50.0 mL of 0.20 M NH3 (Kb=1.8 x 10^-5) with 0.20 M HNO3....
Titrations. Determine if the equivalence point (from the acid/base titration curve) will be equal to pH 7, will be lower than pH 7, or will be greater than pH 7 in the solutions below. Strong acid/strong base Weak acid/strong base Strong base/weak acid Rank the acids in order of increasing acidity: H2O, H2S, H2Se H3PO4, H2PO2, H3PO5
Question 14 What is the pH at the equivalence point in a strong acid-weak base titration? -2 7 less than 7 16 greater than 7
TRUE or FALSE: For every weak acid-strong base titration, the equivalence point will have a pH that is greater than 7
17. Consider the titration of a weak base (such as NH) with a strong acid (suc The pH of the solution at the equivalence point of the titration will be A) greater than 7.00 B) equal to 7.00 C) less than 7.00 D) none of the above
Question: In the figure below, titration curves for strong acid with strong base and weak acid with strong base are shown. Compare the shapes of these curves early in the titration for three different cases: titration of a strong acid, titration of a weak acid with a lower pKa, and titration of a weak acid with a higher pKa. Discuss with the class why the titration curve for weak acids increase more rapidly early in the titration than do stronger...
consider the titration of a weak monoprotic acid (HA) with a strong base. If the titration has begun, but the equivalence point has not yet been reached, which of the following is true: A) The solution is a bugger and the HH equation can be used to compute the solution pH B) The excess titrant will dominate and control the pH at this point C) The dissociation of the weak acid to donate protons will determine pH - make a...
A pH of less than 7 can be realized at the equivalence point during the titration, at 25 oC, of: a) strong acid-strong base titration b) weak acid- strong base c) weak base-strong acid d) none of these
