Analyte is the substance whose concentration is not known before hand and we need to determine its concentration by titration
Here we know HCl concentration.
So, HCl is titrant.
We don’t know NaOH concentration.
So, NaOH is Analyte
Answer:
HCl is the titrant
NaOH is the analyte

The flask contains 10.0 mL of HCl and a few drops of phenolphthalein indicator. The buret contains 0.210 M NaOH. It requires 16.4 mL of the NaOH solution to reach the end point of the titration. What is the initial concentration of HCI? concentration: MHCI URILE
If 32.12 mL of 3.77 M hydrochloric acid solution, HCl, are titrated with 51.5 mL of sodium hydroxide solution, NaOH, according to HCl(aq) + NaOH(aq) - NaCl(aq) + H2O(1) what is the concentration of the sodium hydroxide solution? (Enter your
I'm doing a titration lab tomorrow and I am not sure what the
formulas are to calculate the moles of NaOH, the moles of
HCl, and the molarity of HCl.
The objective of this laboratory is to determine the molarity of
a hydrochloric acid solution using a known concentration of sodium
hydroxide as the titrant.
volume of HCl in flask: 25.00 mL
the net ionic equation for the reaction is:
H+(aq) + OH-(aq) --> H2O(l)
I don't have the data...
