Type your answer here... bromine is very reactive species.so it is not suitable for titration .
Acetic anhydride and aniline are the reactants for the preparation of acetaanilide.
Add concentrated sulphuric acid to the mixture
We could add HCl to the mixture of Zinc and Gold and see which one appear to separate first.
add more H+ to the mixture. or remove the amount of OH-
To aniline, we add Sulphuric acid at 180.C. This will give us Sulphanilic acid. C6H5NH2+H2SO4-------->C6H5 NH3+HSO4-------455 to 475.K-----> C6H5NH2SO3H <=>C6H5NH3+SO3- (zwitter ion)
When using front-end estimation, first you add the front-end digits. Then adjust by estimating the sum of the remaining digits. Then add the two values
When using front-end estimation, we add or subtract the front digits, and then adjust for a more accurate estimation by estimating the sum of the digits to the right of the decimal point.
First add HNO2 or NaNO2+dil.HCl below 5 degrees celcius.Then add CuCl+HCl.
Acetic anhydride and aniline are the reactants for the preparation of acetaanilide.
It is easier to simply add two one-digit numbers than to mess about with estimation!
The color will be a fairly strong red as it is a very strong acid in the pH scale.
It means using only the first non-zero digit (rounded up if required), and replacing all other digits by zero.
If your recipe is like mine, you have a thickened lemon mixture that you add egg to. Put some of the hot mixture in the beaten egg stirring it all the time. Add about a third of the mixture to the egg to warm it up and then add that mixture back into the rest of the lemon mixture. Stirring all the time so that the egg will not cook in lumps.
Add concentrated sulphuric acid to the mixture
you add some water to the mixture :D
add cold water to the mixture
Normally, you only add distilled water.
