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}

<u>Answer:</u> The new pressure will be 101.46 kPa.
<u>Explanation:</u>
To calculate the new pressure, we use the equation given by Gay-Lussac Law. This law states that pressure is directly proportional to the temperature of the gas at constant volume.
The equation given by this law is:
where,
are initial pressure and temperature.
are final pressure and temperature.
We are given:
By using conversion factor: 
Putting values in above equation, we get:
Hence, the new pressure will be 101.46 kPa.
Answer:
134.397 Joules
Explanation:
Using the formula:
E = C × m × Δθ (where E is Energy, C is specific heat capacity and Δθ is change in temperature)
So E = 0.45×5.45×(79.8-25)
So E = 134.397 Joules
