Titration Calc: 0.01M NaOH & 10mL Ethanoic Acid pH

In summary, titration is a technique in chemistry used to determine the concentration of an unknown solution by reacting it with a known solution. It works by slowly adding the known solution to the unknown solution until the reaction is complete. Sodium hydroxide (NaOH) is commonly used as the known solution and its concentration is important in calculating the concentration of the unknown solution. As NaOH is added, the pH of the ethanoic acid solution will change until it reaches a neutral level at the endpoint of the titration.

Lol thanks man.

The next part of the question says: A second titration is carried out in which 0.01 mol L NaOH is titrated with 10ml of 0.200 mol L HOBr, a weak acid with a pKa of 8.69.
Calculate the initial pH and the pH at the eqivilence point.
 

1. What is the purpose of titration?

Titration is a technique used in chemistry to determine the concentration of an unknown solution by reacting it with a known solution. This process is commonly used to find the concentration of acids or bases in a solution.

2. How does titration work?

In titration, a known solution is slowly added to an unknown solution until the reaction between the two is complete. The endpoint of the reaction is determined by using an indicator or by measuring the pH of the solution. From this, the concentration of the unknown solution can be calculated using the known concentration of the other solution.

3. What is the role of NaOH in this titration?

Sodium hydroxide (NaOH) is a strong base that is commonly used in titration as the known solution. It reacts with the ethanoic acid in the unknown solution to determine its concentration.

4. Why is the concentration of the NaOH solution important in this titration?

The concentration of the NaOH solution is crucial in this titration because it is used to calculate the concentration of the unknown ethanoic acid solution. If the concentration of the NaOH solution is known, the concentration of the unknown solution can be determined using the volume and reaction stoichiometry.

5. How is the pH of the ethanoic acid solution affected by the titration with NaOH?

The pH of the ethanoic acid solution will change as the NaOH solution is added. Initially, the pH will be acidic due to the presence of ethanoic acid. As the NaOH is added, it will react with the ethanoic acid and neutralize it, causing the pH to increase. At the endpoint of the titration, the pH will reach a neutral level (pH = 7) due to the complete reaction between the two solutions.
