HOW CAN TITRATION BE USED TO FIND OUT WHICH TYPE OF EGGS HAVE THE BEST EGGSHELL?
DEFINITIONS
Titration
A technique used to determine the concentration of a substance in a solution
Eggshell quality
Durability when reacted to acid
How welll can it withstand acid
Time taken for eggshell to be fully dissolved in acid
Advantage: Easy to measure
Disadvantage: Time taken might be long
Volume of acid measured to dissilve eggshell
Advantage: Precise and can be analysed easily
Disadvantage: Systematic errors might occur due to the equipment measurements,
Thickness, strength, calcium carbonate content
Types of eggs
Different types of eggs may have varying eggshell qualities
Experiments that can be used to find out the best eggshell
Can be used to measure the amount of acid required to completelt react with calcium carbonate in the eggshell sample
Observe the eggshell strength by measuring its resistance to acid (Non-titration)
Measuring time
Advantage: Easy, quick.
Disadvantage: Takes a long time
Crushing eggshells into pieces before doing the experiment
Amount of Carbon dioxide released in a specific time
Advantage: Precise, high validity
Disadvantage: Need of specific equipment in order to measure the amount of gas released.
Crushing eggshells into pieces before doing the experiment
Ability to neutralize acid (Titration)
Using pH indicator to find the endpoint
Equation: CaCO₃ (s)+2HCl (aq)→CaCl₂ (aq)+H₂O (l)+CO₂ (g)
Using pH indicator to find when the solution change color
The faster it change the color, the weaker the eggshell (low calcium carbonate)
Advantage: Easy to know when the reaction ends.
Limitation: Different amount of pH indicator solution used can result in different color change, leading to inaccurate readings.

Volume of acid used until the reaction is complete
Equation: CaCO₃ (s)+2HCl (aq)→CaCl₂ (aq)+H₂O (l)+CO₂ (g)
Finding the endpoint by watching the reaction. (No more bubbling occurs)
The greater amount of acid used, the eggshell contains more caqlcium => stronger
Advantage: Does not require an indicator, can be carreid out easily.
Disadvantage: Hard to know when the experiment ends. The equipment must be in precise readings or it will affect the result.
