1. Functional Dependency (FD)
A functional dependency A → B means: if you know the value of attribute A, you can always determine the value of attribute B. In other words, no two rows can have the same A value but different B values.
Example:
In a table Student(StudentID, Name, Email):StudentID → Name, Email
(Given a StudentID, the Name and Email are always uniquely determined.)
A relation is in BCNF if, for every functional dependency X → Y, X is a superkey

HCl.
Theory:-
Titration of strong acid and strong base involves neutralization
reaction.
NaOH + HCl → NaCl + H2O
During titration pH of the solution taken in the conical flask changes as
the other solution is added from the burette. If NaOH is added from
the burette and HCl is taken in the conical flask, during the titration pH
of the solution in the conical flask will increase.
Procedure:-
1. Take a clean burette and rinse it with 0.1 M NaOH solution and
then

1. Compare text files and binary files with respect to storage, processing speed, memory utilization, and applications.
| Basis | Text Files | Binary Files |
|---|---|---|
| Storage | Data is stored as characters (ASCII/Unicode). Numbers are stored in readable form. | Data is stored in binary (0s and 1s) in the format used by the computer. |
| Processing Speed | Generally slower because data may need to be converted between characters and internal formats. | Generally faster |
