What is the effect of adding the sulfuric acid before KI in iodometric titration?
Adding sulfuric acid before KI in an iodometric titration helps to acidify the solution and prevent the premature oxidation of iodide ions to iodine. This ensures that the iodide ions react with the analyte (substance being tested) instead of being oxidized by any oxidizing agents present in the solution. Acidifying the solution also helps to stabilize the iodine formed during titration.
Effect of oxidizing agents on iodometric titration?
Oxidizing agents can interfere with iodometric titration by oxidizing iodide ions to iodine prematurely, leading to an inaccurate measurement of the analyte's concentration. This interference can be minimized by adding a reducing agent to the titration solution to consume any excess oxidizing agent before reacting with the iodide ions. Additionally, careful selection of the titration conditions and proper sample preparation can help mitigate the effect of oxidizing agents on the titration results.
How do oxalic acid and sulfuric acid differ during titration?
Sulfuric acid has hydrophilic properties when concentrated, so it may have some effect on the reaction taking place. Oxalic acid is an reducing agent, so in titrations - which usually involve some kind of redox - it may begin reacting in ways not intended.
Why addition of water to the vinegar does not effect the determination of its concentration in titration?
Yes, it DOES effect the concentration (mol per litre). This is because the volume (of solution, litres) has changed, when diluting, but not the total quantity (just moles of 'reacting' vinegar in the titration).
What one of the following statements about sulfuric acid is correct sulfuric acid has little effect on metals sulfuric acid is dangerous to living organisms sulfuric acid is a strong oxidizing agent?
dangerous to living organisms

Is there such a thing as sulfuric acid poisoning?
No, you cannot be poisoned by sulfuric acid. You will die from internal hemorrhaging resulting from the corrosive effect of concentrated sulfuric acid before you are poisoned by it.

What is the effect of discolored agno3 in the titration with kscn?
Discolored AgNO3 in the titration with KSCN may indicate the presence of impurities or decomposition of the solution. This can lead to inaccurate results in the titration as the discolored solution may not react as expected with KSCN. It is important to use a fresh and clear AgNO3 solution for accurate titration results.
What effect does temperature have on a strong acid strong base titration?
Temperature can affect the reaction rate of the strong acid-strong base titration. An increase in temperature can accelerate the reaction rate, leading to a faster titration process. This can be advantageous in terms of quicker analysis, but it is important to maintain a consistent temperature throughout the titration for accurate results.
What is tritation?
"Titration" or "titrated" in chemistry, refers to adding one chemical to another, a little bit at a time, to get the two chemicals to provide a certain reaction."Titration" or "titrated" is used medically to figure out drug dosages in at least two ways.1.) It may be to take as little of a drug as possible to get the desired effect. For example, the doctor may start you on 10 mg, and if that is ineffective, gradually increasing the dose to get the maximum effect with the least amount of the medication.OR2.) Often used in treatments such as chemotherapy, this method is where you gradually add the drug/treatment dose until the side effects outweigh the benefit of the drug, which is normally only done in the early stages of clinical trials.Reference: http://patients.about.com/od/glossary/g/Titration-Or-Titrated-The-Definition-Of-Titration-Or-Titrated.htm
What is role of buffer solution in complexometric titration?
In complexometric titration, a buffer solution is used to maintain a constant pH throughout the titration process. This helps to ensure that the conditions are optimal for the formation of the metal-complex, leading to more accurate and reliable results. The buffer also helps to minimize the effect of changes in pH on the endpoint of the titration.

I believe that is Venus.
