Sodium hydroxide is not an unknown solution.
your unknown solution made methyl red turn yellow. it also made phenolphthalein stay clear. what rang of pH does your unknown solution have?
dilute hydrochloric acid
This solution may be toxic, corrosive or radioactive.
magnesium
Sodium hydroxide is not an unknown solution.
Freezing point depression is more significant if a molecule dissociates. It is the molality of the solution of osmotically active particles and freezing/melting point constant (k) of the solvent that determine the magnitude of freezing point depression. In these experiments, we are usually measuring freezing point depression to determine molar mass of the unknown solute. The calculated molar mass would be would be lower than the actual mass of the intact molecule. If you have half as many intact particles, the intact molecular weight must be double to obtain the same formula ratio: MW = g / mol ... since mol actually less of the intact particle, MW must be more
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.
Indicators contain chemicals that will react with certain substances. If that substance is present in your unknown solution, a reaction will occur. If no reaction occurs, then that substance is not present in your solution
Equations are used to find the solution to the unknown variable.

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.
This is still mostly unknown.
Dip a copper coin in that unknown solution And make that solution slightly acidic. After about one hour, take out the copper coin and if there are green colours deposits then there is sulphate, otherwise not.
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.
