An unknown substance is added to a solution and the pH increases The substance is best described as what?
The unknown substance would have to be a basic solution. At least more basic than the initial solution. The pH scale ranges from 0,Most acidic, to 14, Most Basic. If the pH of your solution increases when the unknown substance is added, then it would lead you to believe that the added substance is of a basic nature.

What is a standard solution and how is it used in titration?
A standard solution is a solution with a known concentration of a substance. In titration, a standard solution is used to determine the concentration of another substance by reacting the two solutions until a chemical reaction reaches completion. The volume of the standard solution needed to react completely with the unknown solution is used to calculate the concentration of the unknown substance.
What is the purpose of adding an indicator to an unknown solution?
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
What is titrate?
Titrate is a process used in chemistry to determine the concentration of a substance in a solution. It involves slowly adding a solution of known concentration (titrant) to another solution until a reaction is complete, allowing the concentration of the unknown substance to be calculated.
What unknown quantity can be calculated after performing a titration?
Titrations can be used to work out the initial amount of moles of a substance (for instance the number of moles of iron in a tablet).
How to use stoichiometry determine the concentration of a substance?
To use stoichiometry to determine the concentration of a substance, you need to first balance the chemical equation for the reaction involving the substance. Next, determine the moles of the known substance and use the balanced equation to relate it to the moles of the unknown substance. Finally, calculate the concentration of the unknown substance in terms of moles per liter based on the volume of the solution.

a catalyst
How do you test for monosaccarides?
You place Benedict's solution (blue solution) and the unknown substance (possibly containing monosaccarides) into a beaker and then heat it for approximately 5 minutes. If the substance contains monosaccarides, the solution will turn from blue to orange.

Is sodium hydroxide unknown solution?
Sodium hydroxide is not an unknown solution.
What is the purpose of titration?
The process of Titration is used to determine the unknown concentration of a known reactant, such as acid. It is used industially to find the strength of acid so it can be used for other things.
What is the product of every titration?
The product of a titration is the determination of the unknown concentration of a substance (analyte) in a solution by reacting it with a solution of known concentration (titrant) until an endpoint is reached. This helps in quantifying the amount of the analyte present in the sample solution.
What is a titration reaction?
A titration reaction is a chemical technique used to determine the concentration of a substance in a solution. It involves the gradual addition of a known concentration of another substance, called the titrant, to the solution until a reaction is complete. The endpoint of the reaction is usually detected using an indicator or an instrument, allowing for the calculation of the concentration of the unknown substance.
What is titration in water used for?
Titration in water is commonly used to determine the concentration of a specific solute or substance in a solution. It is a technique where a known concentration of a reagent (titrant) is added to a solution until the reaction reaches an endpoint, which indicates the equivalence point and helps calculate the concentration of the unknown substance.
