Here a catalyst is a substance that lowering the activation of a chemical reaction and finally increases the rate of reaction without involving in the reaction process it just alter the speed of reaction without effecting the position of equilibrium and catalyst must remained unchanged in mass chemical composition at the end of the reaction.
In the above scenario it mentions that HCl is being used up during the reaction process so HCl is not a catalyst

The reaction of an acid such as HCl with a base, such as NaOH, in water is an exothermic reaction. HCl(aq) + NaOH(aq) ---> NaCl(aq) + H2O In one experiment, a student placed 55.0 mL of 1.00 M HCl in a coffee-cup calorimeter and carefully measured its temperature to be 35.5oC. To this was added 55.0 mL of 1.00 M NaOH solution whose temperature was also 35.5oC. The mixture was quickly stirred, and the student noticed that the temperature of...
