phenanthroline is used as a redox indicator

titration is the best method to determine the unknown concentration of the unknown. if ur known is a solid then you would have to used distilled water to ensure it is submerged before you titrate.
Phenolphthalein is a pH indicator that changes color in response to different pH levels. By using phenolphthalein, you can determine if a solution is acidic or basic based on the color change it exhibits. This can help you identify unknown substances by comparing the color change with known pH values of different substances.
To determine if a solution is a buffer, check if it contains a weak acid and its conjugate base, or a weak base and its conjugate acid. Alternatively, you can test the solution's pH - buffers resist significant changes in pH when small amounts of acid or base are added.
Acetic acid is added to the solution, but the pH of the solution does not change. Sodium hydroxide, a base, is added to the solution, but the pH of the solution does not change.
Phenanthroline solution is added to unknown iron solution to form a red-colored complex with iron ions. This complex is then used for colorimetric analysis to determine the concentration of iron present in the solution.

A standard solution is a solution of known concentration used in titration to determine the concentration of an unknown solution. It is usually added to the unknown solution until a desired reaction is completed, allowing the concentration of the unknown solution to be calculated based on the volume of standard solution used.
The substance is likely a base, as bases typically lead to an increase in pH when added to a solution. Bases are substances that can accept protons or release hydroxide ions, causing the solution to become more basic.
Titration is a laboratory technique used to determine the concentration of an unknown solution by reacting it with a solution of known concentration. A burette is used to carefully add the known solution to the unknown solution until a chemical reaction reaches completion, indicated by a color change or other observable signal. The volume of the known solution added is used to calculate the concentration of the unknown solution.
In a titration, a solution of known concentration (the titrant) is slowly added to a solution of unknown concentration until the reaction is complete. This reaction can be monitored using an indicator that changes color when the reaction is complete. The volume of titrant required to complete the reaction can then be used to determine the concentration of the unknown solution.

In fact, a back titration is carried out as in a very similar method to an ordinary titration. the only difference is in the context. Consider an unknown acid solution. Then a known amount of excess alkali was added to the solution and made them react. Then the process of finding the amount left from the alkali is known as the back titration.
A pH curve is a graph that shows how the pH of a solution changes as a particular chemical reaction or process occurs. It typically displays the pH on the y-axis and the volume of titrant added on the x-axis to help visualize how the pH of the solution changes with the addition of an acid or a base. pH curves are commonly used in acid-base titrations to determine the equivalence point and identify the unknown concentration of a solution.
In titration, the titrant is a solution of known concentration that is added to the analyte (solution of unknown concentration) to determine its concentration. The titrant reacts with the analyte in a chemical reaction, allowing for the determination of the analyte's concentration based on the volume of titrant required to reach the equivalence point.
In titration, a solution of a known concentration is called the standard solution or titrant. It is used to react with the analyte solution of unknown concentration to determine the concentration of the analyte. The titrant is added to the analyte solution until the equivalence point is reached, signaling the end of the titration.
ammonium oxalate is added to calcium carbonate because in the reaction between the two a crystal is formed that contain the Ca+2 ion. This is useful because if you have a sample of sodium carbonate with an unknown molarity you can use the oxalate to extract this calcium and determine what the molarity of the unknown solution was
