Solutions

Solutions can be considered as homogeneous mixtures which contain two or more than two chemical substances. The chemical substance which is the greater part is defined as solvent. And the chemical substance that is dissolved in a solvent is referred to as solute. Solution chemistry plays an important role in chemistry since it supports many commercial applications of solutions.

Procedure A student used a pH meter to collect data for the titration of an unknown concentration of ethanoic (acetic) acid with a 0.150 mol/L solution of sodium hydroxide. The data table from the investigation is shown in the table below. & Enter the data from the table into a spreadsheet program. Use the program to plot the results, with pH on the vertical axis and volume of base added on the horizontal axis. Make sure you enter labels for each axis, and provide a suitable title for your graph. Print your graph. Titration of Ethanoic Acid with Sodium Hydroxide Volume of ethanoic acid = 25.00 ml [NaOH] = 0.150 mol/L b On your graph, shade the buffer region. Identify the pH range of an indicator suitable for this titration. Name two indicators that would have endpoints suitable for this Volume of NaOH(aq) Added (mL) pH titration. None 2.83 C The titration curve should show a steep change in pH near the equivalence point. Choose a point halfway along the portion of rapid change on the…
