Reactions : AcidBaseRxns (20 Variations) In order to answer the following questions, write the net ionic equation for the reaction between equal volumes of 0.10 M solutions of the following acid and base:
KOH(aq) + HBr(aq)
What are the reaction products? Does the reaction yield an acidic, basic, or neutral aqueous solution?
A 25.0 mL aliquot of a 1.44M solution of ammonia (Kb = 1.8 x 10-5) is titrated with 1.50M HCl. Use the Indicator Table below to decide which of the indicators listed would most accurately signal the equivalence point for this titration.
Write the letter corresponding to your choice of indicator in the box.
