Determine the molarity of Na2Co3 solution with the help of supplied M/10 H2So4 solution by titration method
Well, I don't mean to be salty, but let's dive into the answer. Molarity, also known as the concentration of a solution, can be determined using the equation:
M1V1 = M2V2
Where M1 is the molarity of the initial solution (M/10 H2SO4), V1 is the volume of the initial solution used, M2 is the molarity of the final solution (Na2CO3), and V2 is the volume of the final solution.
So, if you titrate M/10 H2SO4 against Na2CO3, you measure the volume of M/10 H2SO4 used until the reaction is complete. From there, you can plug in the values into the equation to determine the molarity of the Na2CO3 solution.
Just remember, while chemistry can be titrifying, you've got this in the bag!
To determine the molarity of Na2CO3 solution by titrating it against M/10 H2SO4 solution, you will need to follow a step-by-step process. Here's how you can go about it:
Step 1: Preparation
- Gather the necessary equipment: burette, pipette, conical flask, beaker, indicator (phenolphthalein), and distilled water.
- Make sure the burette and pipette are clean and properly calibrated.
Step 2: Standardization of M/10 H2SO4 solution
- Fill the burette with M/10 H2SO4 solution.
- Use a pipette to measure a volume of the Na2CO3 solution into a conical flask (let's say V mL).
- Add 2-3 drops of phenolphthalein indicator to the conical flask.
- Titrate the Na2CO3 solution by gradually adding H2SO4 from the burette into the conical flask while gently swirling the flask.
- Observe the color change of the solution from pink to colorless.
- Record the volume (V') of H2SO4 required to reach the endpoint (when the color turns colorless).
Step 3: Calculation
The balanced equation for the reaction between Na2CO3 and H2SO4 is:
Na2CO3 + H2SO4 -> Na2SO4 + H2O + CO2
From the balanced equation, we can see that 1 mole of H2SO4 reacts with 1 mole of Na2CO3.
- Calculate the number of moles of H2SO4 used in the titration:
Moles of H2SO4 = (Molarity of H2SO4) x (Volume of H2SO4 used in the titration in liters)
- Since the molarity of H2SO4 is M/10, substitute this value into the equation:
Moles of H2SO4 = (M/10) x (V'/1000) moles
- Equating the moles of H2SO4 with the moles of Na2CO3:
Moles of Na2CO3 = Moles of H2SO4
- Since 1 mole of Na2CO3 reacts with 1 mole of H2SO4, the molarity of Na2CO3 can be calculated using the volume of Na2CO3 used in the titration (V mL):
Molarity of Na2CO3 = Moles of Na2CO3 / (Volume of Na2CO3 used in titration in liters)
= (M/10) x (V'/1000) / (V/1000)
= (M x V') / V
The final value obtained will be the molarity (M) of the Na2CO3 solution.
Remember to repeat the titration process at least three times to ensure accurate and consistent results.
