In a laboratory experiment, a student titrates 10.0 mL of acetic acid, CH3COOH, solution with 0.5 M NaOH. The endpoint was reached when 46.00 mL of 0.50 M NaOH were delivery. What was the concentration of acetic acid in the solution

Concentration of acetic acid=2.3mol/L

Explanation:

Write the balanced chemical reacion:

N1 and N2 normality of CH3COOH and NaOH respectively;

V1 and V2 volume of CH3COOH and NaOH respectively and they are taken upto end point of titration;

we have given molarity but we need normality;

but in case of NaOH and CH3COOH n-factor is 1 for each.

hence

normality=molarity;

Concentration of acetic acid=2.3mol/L

answer seismograph;

the formula for the conversion of temperature from degree celsius to kelvin is:

the sample of water at is converted to kelvin temperature by using the above formula as:

on comparing the two samples of water at or we can say that at and at respectively. the difference between the temperatures of two samples of water is:

hence, one can say that the sample of water at is greater than the sample of water at by .
