Can you use indicator other than phenolphthalein in the titration of NaOH?
Yes you can use methyl red, methyl orange, bromophenol blue and other indicators instead of phenolphthalein in the acid-base titration of NaOH.
Why methyl orange is used in titration of weak base against weak acid?
It is the best indicator for the situation. For other combinations of acids and bases other indicators are suited better. mostly it is because of how easy their colour changes or how obvious they are.
When testing an unknown solution how can you tell if it is acidic basic or neutral?
Simple method is to use a pH testing kit. A more complicated method would be to perform a titration using methyl orange (or some other indicator).
What are some other ways that acid base titrations are used?
Acid-base titrations are usually conducted with an indicator. Indicators are used to measure the end point precisely. Some of common indicators are methyl red, methyl orange and bromothymol blue.
What are chemical indicators?
There are five chemical indicator of a chemical change that include color changes and gas produced. The other indicators are odor released temperature changes, and new substance formed.

Besides water what other solvent can be used to separate screened methyl orange?

Why potentiometric titration instead of direct titration?
Potentiometric titrations are based on standard electrode potential change observed through potentiometer. But direct titrations are based on physical observation on color change by a human. In other words the detection of the endpoint can be noted from significant change in the voltage or millivoltage value in the case of potentiometric titration. So both precision and accuracy can be achieved in potentiometric titration.But in the case of direct titration using an indicator, change in the color is the criteria and the observation of color change can vary from one person to other and so both precision as well as accuracy cannot be achieved. For instance in an acid-base titration using methyl orange indicator, the color change observation is significantly vary from person to person.Moreover in potentiometric titration the equivalence point (different from end point and equivalence point is more accurate than end point) can be noted from a second derivative graph. So pinpoint accuracy over the titration results can be accomplished in a potentiometric titration.ByDr M Kanagasabapathy PhDAsst.

Why KmnO4 is used as self indicator?
As we all know that the potassium permanganate (KMnO4) is the dark purple color solution ...and in titration it become colorless ....so when the titration is completed ...and the other single drop of KMnO4 solution produce pinkish colour in a beaker ...which indicate that the reaction was completed just a single drop before .. we use indicator in a a reaction in order to indicate ...but we dont used indicator in titration with KMnO4 because it also indicate us by changing its color ...colorless to pink
What are the main 3 indicators?
litmus paper and pH scale i am not sure about the rest :)
Ph color for 1?
Red/pink for litmus indicators. Other indicators such as methyl orange will display different colours.
Detect equivalence point in titration without an indicator?
Titration without indicator is only possible with another measurement:Examples / possibilities:pH-electrode measurement (acid-base titration)Conductivity measurement (acid-base titration or ion-reaction)Change of color by excess or depletion of the reactant/titrant (redox titration)Precipitation by excess or depletion of the reactant/titrantAdded:(The following was more or less written for 'indicator' titrations, but same principles count for other 'sharply' changing properties):The equivalence point is the point where the number of moles of titrant equal the number of moles of the reactant. The end point is the point where the indicator being used changes color (also 'indication point)'.If the indicator is chosen correctly, the end point will essentially be as near as possible at the equivalence point.The point of the titration is to find the equivalence point -- the end point is just a very close approximation to it. This is because the pH of the solution changes very rapidly close to the equivalence point.Therefore, the indicator will change color very close to the equivalence point because of the steepness of the pH change
What is an indicator blank?
During an experiment for chemistry, if an indicator will not work due to the lack of a reactant, the reactant can be added. You must then compensate for the added amount by creating a solution of the indicator and the the same amount of the reactant. The volume required in the blank titration must then be subtracted from the other results to obtain quality results. This is an indicator blank and how it is used.
