Introduction
Antacids are basically bases that react with acid stoichiometrically. The number of acids moles
that will be neutralized by a single antacid tablets will be evaluated by back titration. To perform
the above experiments, a tablet will be dissolved in a well-known excess quantity of acid. The
subsequent solution will be acidic as the tablet will not offer sufficient moles of base to fully
neutralize acid (Chandra, Kishore and Ghosh 2015). The resultant solution will be titrated using
base of known strength to assess the quantity of acid not neutralized by the antacid tablet. To
figure out the number of mole of antacid tablets, the moles of acids neutralized was deducted
from the moles of acid present in the initial solution (Alalor, Avbunudiogba, Builders and
Okpara 2019).
The strength of an acid is a measure of the degree of ionization in an aqueous solution. The
greater the number of ions dissociated, or the number of cations and anions released in solution,
the stronger the acid. For example, hydrochloric acid (HCL) dissociates completely into H+ and
Cl- ions in solution, so it is very strong. Acetic acid (CH3COOH), which is found in household
white vinegar, releases few ions in solution, so it is considered to be a weak acid.
The concentration of an acid is a measure of the amount of available acid ions dissolved in a
solvent. Concentration can be measured in moles, parts per million or percentage. The
concentration is a ratio of the solute to solvent content of a solution. Acidic solutions with low
numbers of available ions in solution are called dilute solutions whereas those with high numbers
of available ions are called concentrated solutions.

Acid- base titration is a quantitative analysis method to determine an acid’s or bases’
concentration by precisely neutralizing them with a standard solution of either acid or base of
known concentration. It is monitored with the help of a pH indicator to know the development of
the acid-base reaction.
HA+BOH→BA+H2O
Acid + Alkali→Salt + Water
Or H+ + A– + B+ + OH– → B+ + A– + H2O
Or H+ + OH– → H2O
The acid-base titration is based on the reaction that neutralization is between a base or an acidic
and analyte. In this type, a reagent is mixed with the sample solution until it reaches the required
pH level. This type of titration majorly depends on the track change in pH or a pH meter.
Titration is actually a quantitative chemical evaluation that is utilized the strengths of a known
solution, which is molarity. The above idea is used to assess the neutralized moles of HCl. A
second reactant in the burette dispenses the solution into a conical flask containing another
reagent. Indicators are organic substances that changes color reliant on the solution pH. In the
basic solution, the indicator would change to pink while in the acidic solution, it would remain
clear (Rally et al. 2016).
Volumetric analysis is a quantitative analytical method which is used widely. As the name
suggests, this method involves measurement of the volume of a solution whose concentration is
known and applied to determine the concentration of the analyte. In other words, measuring the
