Answer:

#pH# #=# #-log_10[H_3O^+]#. Given the negative logarithmic scale, simple addition of #HCl(aq)# will lower #pH# substantially.

Explanation:

Given the negative logarithmic scale, increasing #H_3O^+# concentration will substantially reduce #pH#.

The acid that we buy commercially, approx. #"35% w/w"#, is about #10*mol*L^-1# with respect to #HCl#.

I hope I don't insult your intelligence when I remind you that #"muriatic acid "=" hydrochloric acid"#.
