Determine the MAX amount of titrant you will possibly need for your titration.
Your unknown solution has been prepared by dissolving btw 0.05-0.09mol of zwitterion form of the amino acid in 1L of ~ 0.1M HCl solution.
you will titrate 50mL of that amino acid with 0.5M NaOH.
Assume that the amino acid concentration of 0.0900mol per L of 0.1 M HCl
Please help me...I don't uderstand what to do. Explanation will help greatly.
To determine the maximum amount of titrant you will possibly need for your titration, follow these steps:
1. First, determine the number of moles of the amino acid present in the 50 mL solution you will be titrating.
- You are given that the concentration of the amino acid is 0.0900 mol/L in 0.1 M HCl solution.
- Convert the concentration to moles per mL: 0.0900 mol/L * (1 L / 1000 mL) = 0.0000900 mol/mL.
- Multiply the moles per mL by the volume (50 mL) to get the number of moles in the 50 mL solution: 0.0000900 mol/mL * 50 mL = 0.00450 mol.
2. Next, consider the stoichiometry of the reaction between the amino acid and NaOH.
- The balanced chemical equation for the reaction might look like this: Amino acid (1:1) NaOH.
- This means that the ratio between the moles of amino acid and NaOH is 1:1.
- So, the maximum amount of NaOH (titrant) required will be equal to 0.00450 mol.
Therefore, the maximum amount of titrant (0.5 M NaOH) you will need for the titration is 0.00450 mol.
The explanation above breaks down the steps involved in determining the maximum amount of titrant required for a titration. By understanding the concentration of the amino acid and using stoichiometry, you can calculate the necessary amount of titrant needed for an accurate titration.
