What is The process of adding a known amount of solution of known concentration to determine the concentration of another solution is called?
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.
What is the purpose of adding water to the base?
To prepare a dilute solution.
IronIII reacts with thiocyanate to form a red complex formula. what change we will observe if we add a solution containing ironIII to this mixture?
According to Le Chatelier principle, adding more reactants will force equilibrium to favor products. The solution will become more red.
How do you find conjugate acid?
By adding one (1) proton (H+ ion) to the base formula:example:(base ammonia) NH3 + H+(proton) --> (conjugated acid ammonium ion) NH4+
What is the purpose of adding Lugol's iodine to potato slide?
To stain the starch in the leucoplasts so they are visible
What is the purpose of adding dextrin in titration?
In a precipitate titration, dextrin is added to prevent the precipitate from coagulating during titration. It also makes the color change more visible, since some analytes may be difficult to see a color change during the titration. I hope this helps! This is straight out of my Analytical Lab manual.
Why do you have to heat up the solution of oxalic acid after adding sulphuric acid for the titration with permanganate?
To act as a catalyst
What is the trial titration?
A trial titration is carried out before the actual titrations and is not recorded. It is carried out by adding increments of several milliliters from the reactant in burette. It helps to give a rough estimation to the end point.
What is the manipulative variable of the separation of ammonium chloride sodium chloride and sand HELP?
Adding water sodium and ammonium chloride are easily dissolved; by filtration of the solution sand is separated, remaining on the filter.
How can you test for precence of barium ion in aqueos solution?
Adding Ammonium Carbonate should give a White precipitate
What is the purpose of adding sugar to cookie dough?
The purpose is to make it sweet.
What is titration used in the medicine industry?
Medicine is uses to reduce a patient until they are heal. In particularly in chemistry is it the process of finding a concentration of a certain reactants in solutions. This functionality, titration is also known as volumetric analysis, due to a heavy reliance on the measurement of volume and concentration. Titration involves taking an agent of unknown concentration and adding it to a solution. The agent is often known as the titrant and the purpose of adding it o a solution is to create a measurable reaction with the unknown agent. The scientists have to find the exact concentration of unknown agent, also known as the analyte. The concentration of the analyte will not found until the reaction has finished. Often the solution that will change colour to give and assessable endpoint to the reaction.
What is A method to determine the concentration of a substance in solution by adding a solution of known volume and concentration until the reaction is done?
The answer to my own question is: TITRATION
What are the purposes of adding so?
There are not much purpose of that.
What is the effect of adding the sulfuric acid before KI in iodometric titration?
Sulphuric acid helps in maintaining pH around 3-4 which further helps in liberation of iodine upon adding KI solution.
Why there is a need to warm the solution of sulfuric acid and oxalic acid during redox titration?
Adding heat to a reaction usually speeds up a reaction.
Why is it permissable to wash the walls of the titration flask with deionized water during the titration?
When you are titrating you are typically neutralizing X amount of moles of analyte by using Y amount of moles of titrant. Adding water doesn't change the amount of moles of analyte, only the concentration.
