How do you prepare phenolphthalein indicator for titration? What type of reaction occurs during an acid-base titration? Why is phenolphthalein used in a titration experiment? When was titration first used? When is back titration used? Distinguish between titrant and titrate.Explore...
CO2 will readily dissolve in distilled water (or any water, but more so in distilled because it's 'empty' water). This can be proven. Add phenolphthalein indicator to distilled water. Let's presume the pH was 7 or just slightly below. the indicator should be a slight pink color. If yo...
How Is Titration Carried Out? The analyte is measured and filled in a beaker. A few drops of an acid base indicator, such as methyl orange or phenolphthalein, is added to the analyte. Phenolphthalein remains colorless in acid, but turns pink in the presence of a base. Similarly, methyl or...
Another example of a classical method for qualitative analysis is the Kastle-Meyer test which employsphenolphthaleinas an indicator to check for the presence of haemoglobin in the given analyte. Flame tests can be used to check for the presence of specific elements in an analyte by exposing it ...
There are different ways of determining the titratable acidity of a sample, but the most common method is a titration with an alkali solution. The most common alkali solution used is sodium hydroxide, along with the phenolphthalein indicator. The equation for the calculation is as follows: ...
What is the color of a phenolphthalein indicator in an acidic solution? 1. A substance with a pH of 9 is considered {Blank}. \\ 2. If red litmus paper is used to test the substance it would turn what color? \\ a. basic; red b. acidic; red c. acidic; blue d. ...
