A 20.00 mL sample of HCl with unknown concentration is titrated with 0.50 M NaOH. a) Write out the balanced equation

b) Write out total ionic equation

c) Write out net ionic equation

d) If 15.0 mL of NaOH was required to reach the equivalence point (point where phenolphthalein turns pink) what is the concentration of the HCl solution. Please include some of your work as best as you can in the answer for full marks.

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
