What would happen if there was no starch in the redox titration?

If you are looking at a iodide to iodine redox titration, the solution would turn yellow instead of blue/black. The blue/black color of the iodine-starch complex is very intense and so the end-point is sharper. Without the starch, the endpoint, when the first yellow from the formation of iodine I2, appears, is less sharp and is harder to see.

Why use sulphuric acid in redox titration?
H2SO4 is a strong acid and will deliver H(+) which will help to proceed the reaction much faster. Thereby, the sulphate-ions barely react in a redoxreaction. If we would take HCl for example, the Cl(-) ions can easily take part in a redoxreaction as a reductor.
What is a titration and what equipment would you need?
A titration is a process of nutrilising an acid. You would need a burette, a beaker and and acidic and alkali substance. Higher chem FTW
What type of reaction would a titration be useful for?
Neutralization.
What problem will happen if you use hydrochloric acid instead of sulphuric acid in titration?
It would change your results because concentrated HCl is more acidic then H2SO4, therefore, there would be a larger change in pH quicker.
Why is starch solution used as indicator in Sodium thiosulphate Iodine titrations instead of phenolphthalein indicator?
Phenolphthalein is an acid base indicator - it does not show the end-point in a thiosulfate type titration. Starch gives a very sharp end-point from a blue-black to colorless end-point when titrating iodine with thiosulfate. Phenolphthalein would just not detect this change.
What would happen if the iodine molecules passed through the membrane into the starch suspension?
The starch suspension would form into a blue-black precipitate. This is due to the reaction between starch and iodine.
What would happen if you added water to a starch molecule?
the water then appears coulerless
What would happen if enzyme amylase is absent in saliavary gland secretions?
Starch and glycogen would not be able to be digested and sugar would not be able to be formed.
What would happen if someone forgot to add the starch to the beverage before they began adding iodine?
you die
What would happen if you poured starch indicator solution into the cell and filled the beaker with starch and glucose solution?
Well what i think is that The water outside of the "cell" will change colors and not the "cell" :D
What happens when you mix starch and iodine together?
what would happen is u would get a result of a blue-black colour at the end..!!brandon was here

What would happen if you didn't eat food with any starch in?
Starch is full of carbohydrates, which is your source for energy fast. Not eating a lot of starch will give you a lack of the sugar that is produced from the carbohydrates when broken down for your cells. Pretty much you'll probably feel a little tired.
