a titration curve of an unknown acid whose equivalence point is at pH 7 segguest that? a) this is a weak acid because the equivalence point of all strong acids is below 7 b) this is a strong acid because the equivalence point of all strong acids is pH 7 c) this is a weak acid because the equivalence point of all weak acids is pH 7 d) this is actually pure water please explain as much as you can. i think...

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
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....
Mark each of the following statements about the ½ equivalence point of an acid-base titration TRUE or FALSE. a. It is the point in the titration when the concentration of weak acid (HA) being titrated is equal to the concentration of the conjugate base (A− ). b. It is the point halfway between the beginning of the titration of a weak acid or weak base and the equivalence point. 2 c. When a strong acid is titrated with a strong...
