17. Which of the following statements aboat fitration curvei is false? a In titration curves for weak acid weak base, pH chinges near the equivalcoce point too small for color changes to be used b. The equivalence point will be basic when titrating a weak acid with a strong bale c. A titration curve for titrating a strong acid strong base will always have an point at pH 0. Gdy The end point of titration is the point where chemically equivalent amounts of acid and 18, e have reacted bow pH changes near the equivalence point. A shows which of followi statements about buffers is the a The pled buffer Molu will no drastically wben small amounts of strong b acid or strong base change A always con of a weak acid or weak base, and a soluble ionic salt of the weak acid or weak ba c.
