Calculate the number of moles of HCl that reacted. Molarity of HCI = 0.10 mol dm3. Now, 1 dm³ is equal to 1 L, so, molarity of HCI is 0.10 mol/L Volume of HCI taken = 25.00 cm³ = 25.00 x 103 L [1 cm³ = 10° L] Moles of HCI reacted = molarity * volume in L = 0.10 mol/L * (25.00 x 10° L) = 2.500 x 103 mol The moles of HCI that reacted is 2.5 x 103 mol. By reference to the reacting ratio of HCl and NaOH, deduce the number of moles of NaOH required to reach equivalence.
Ionic Equilibrium
Chemical equilibrium and ionic equilibrium are two major concepts in chemistry. Ionic equilibrium deals with the equilibrium involved in an ionization process while chemical equilibrium deals with the equilibrium during a chemical change. Ionic equilibrium is established between the ions and unionized species in a system. Understanding the concept of ionic equilibrium is very important to answer the questions related to certain chemical reactions in chemistry.
Arrhenius Acid
Arrhenius acid act as a good electrolyte as it dissociates to its respective ions in the aqueous solutions. Keeping it similar to the general acid properties, Arrhenius acid also neutralizes bases and turns litmus paper into red.
Bronsted Lowry Base In Inorganic Chemistry
Bronsted-Lowry base in inorganic chemistry is any chemical substance that can accept a proton from the other chemical substance it is reacting with.
By reference to the reacting ratio of HCL and NaOH, deduce the number of moles of NaOH required to reach Equivalence.
Btw I did the first part of the question so this is a follow up.

Standardization of NaOH
Method
1
Fill a burette with the solution of NaOH(aq) of unknown concentration.
Pipette 25.00 cm’ of the standard solution of 0.10 mol dm HCI(aq) onto a clean conical flask.
-3
3
Add a few drops of the indicator bromothymol blue solution to the conical flask and stand it on a white tile or
white paper.
Titrate the NaOH against the HCI, until the endpoint of the indicator is observed, and record the volume
added from the burette.
5
Repeat the titration until final values within 0.05 cm³ are obtained.

Analysis
Calculate the number of moles of HCl that reacted.
Molarity of HCI = 0.10 mol dm3.
Now, 1 dm³ is equal to 1 L, so, molarity of HCI is 0.10 mol/L
Volume of HCI taken = 25.00 cm3
= 25.00 x 103L
[1 cm³ = 10° L]

Moles of HCI reacted =
molarity * volume in L
%3D
= 0.10 mol/L * (25.00 x 10° L)
= 2.500 x 103 mol
The moles of HCI that reacted is 2.5 x 103 mol.
