Hi have a titration examination coming up soon and was completely confused by the fact that you could use phenolphalien with a pH range of 8.3-10 on a strong base and strong acid titration which has its equivalence point at pH 7?
Help plsss
Thanks in advance

hi, this might be that the strong acid and strong base reaction produces something that is slightly basic. What are the products of this reaction?

The one we did at school was NaOH and HCl titration, so the product was NaCl

that's strange, so the colour remains colourless?
A NH4OH + HCl reaction would make sense but not NaOH + HCl
