A pH of 6 can be used in complexometric titration when the metal ion being titrated forms a complex with the titrant that is stable at this pH. The choice of pH is important to ensure that the metal ion forms a quantifiable complex with the titrant while minimizing interference from other species present in the solution.

What are different types of indicator used in titration?
Common indicators used in titrations include phenolphthalein (colorless to pink at a pH around 8-10), methyl orange (red at pH <3.1, yellow at pH >4.4), bromothymol blue (yellow at pH <6, blue at pH >7.6), and litmus (red at pH <4.5, blue at pH >8.3). Each indicator changes color at a specific pH range, allowing for the determination of the endpoint of the titration.
What will be the pH at the equivalence point of the titration in question 3?
For strong acid/strong base reactions: pH 7 is the equivalence point For titration of a weak base with strong acid : pH 6-3 is the equivalence point For titration of a weak acid with strong base : pH 8-11 is the equivalence point For weak acid/weak base reactions it is also around pH 7, but it happens so NON-sharply, vague, that titrations can't be used for these.
End point of titration should be at pH?
A titration usually has an acid (pH 0-6) in the burette and an alkali (pH 8-14) in the conical flask below the burette. Your aim is to neutralise the two solutions by titrating them against each other.So the endpoint pH should be 7 (universal indicator/litmus paper will appear a greenish colour). The solution in the conical flask is neutral.Hope this Helps!
How is an indicator used to determine the pH of a solution?
Iodine solution is an efficient indicator for starch. It will go from a light brown colour to a black colour if starch is present and will stay light brown if no starch is present. Hope this Helps!
Which indicator is used for 8-6 pH?
Bromothymol blue (pH 6.0-7.6) Phenol red (pH 6.4-8.0) Neutral red (pH 6.8-8.0)
How can you determine total acidity?
By titration with alkaline on methyl-red indicator (pH<6)

If the equivalence point of a titration is 5 what range of pH should the indicator be?
An indicator should have a pKa close to the expected pH at the equivalence point. For a titration with an equivalence point at pH 5, an indicator with a pKa in the range of 4 to 6 would be suitable for visual detection of the endpoint.
Which indicator is used for 8-6 pH?
Bromothymol blue (pH 6.0-7.6) Phenol red (pH 6.4-8.0) Neutral red (pH 6.8-8.0)
What is the exact pH of acid?
Well, there really is no "exact" pH of an acid. An acid can be a certain pH, before it is considered a base, and to change an acid to a base would be called titration, but lets not get carried away. The pH of an acid can be anywhere between 0-6 on the pH scale, 7 would be neutral, and 8-14 would be considered a base.
What is bromothymol blue and what is it used for?
Bromothymol blue is used as pH indicator: under pH=6 is yellow and above pH=7,6 is blue. For other applications see the link below.
What is a substance which is pH 6?
Natural rainwater (pH 5 - 6) Milk (pH 6 - 6.6)
What have the smallest number hydrogen ions pH 2 or pH 6?
A pH of 2 has a higher concentration of hydrogen ions than a pH of 6. This is because pH is a measure of the concentration of hydrogen ions in a solution, and the lower the pH value, the higher the hydrogen ion concentration.
What is pH 6?
A solution that has a pH of 6 is slightly acidic.
