chemical. During the process of digestion, the food is broken down into smaller molecules. The salivary glands present in our mouth helps in the breakdown of the food. In this process, there is a formation of a new substance. Therefore, it is considered to be a chemical change.
The steps usually involves adding the known solution (the titrant) to a known quantity of the unknown solution (the analyte) until the reaction is complete which can be understood in detail as below with the help of through out process of titration.
<h3 /><h3>What is Titration ?</h3>
A titration is a technique used to work out the concentration of an unknown solution based on its chemical reaction with a solution of known concentration.
Steps in order to determine the concenteration of base solution ;
(Acid-Base Titration)
- Choose the titrant.
- Choose the titrate.
- Select the normality of the titrate.
- Choose the volume of the liquid to be pipetted out.
- Select the indicator.
- Start titration.
- End point is noted at the colour change of the solution.
- From the final reading the normality of titrant can be calculated by the equation:
N₁V₁=N₂V₂
- After finding the normality, the amount of given substance in the whole of the given solution can be calculated by the equation:
Mass = Equivalent weight x Normality \ Volume {1000}

It will react by being a chemical change because something new is formed
Sorry I accidentally touched it
I'll just list down the acidic, basic, and neutral salts.
ACIDIC
<span>THE CATION: is the conjugate acid of a weak base
THE ANION: Conjugate Base of A Strong Acid
</span>Ammonium Sulfate - <span>(NH₄)₂SO₄
</span>Ammonium Chloride - NH₄Cl
BASIC
<span>THE CATION: comes from the cation of a strong Base (i.e. Na+, K+, Li+)
The Anion: comes from the conjugate base of a weak acid
</span>Sodium Acetate - CH₃COONaSodium Phosphate - <span>Na₃PO₄
</span>Calcium Acetate - (CH₃COO)₂Ca
NEUTRAL
<span>THE CATION: comes from a strong base
THE ANION: comes from a strong acid
</span>Sodium Nitrate - NaNO₃
Barium Chloride - BaCl₂Potassium Chloride - KCl
