Is phenolphthalein an indicator?
Yes, phenolphthalein is an indicator commonly used in acid-base titrations to determine the endpoint of the reaction.
A commonly used acid indicator is?
Litmus paper is a commonly used acid indicator. It changes color in response to the pH of a solution, turning red in acidic conditions and blue in basic conditions.
Which indicator is used for the titration of weak acid and strong base?
Phenolphthalein is commonly used as the indicator for the titration of a weak acid and a strong base. It changes color from colorless to pink at the equivalence point of the titration when the weak acid is completely neutralized by the strong base.
What are some indicators?
Indicators are chemicals that change color in the presence of an acid or a base. The most commonly used indicator is phenophthalein.
Name the indicator used in the edta method?
Erio Chrome Black-T, is usually used as indicator. It is commonly known as EBT. EBT can easily form weak complex ,which can be replaced easily by Sequencing agent Ethylene Diammine Tetra Acetic acid
What is the best acid base indicator?
One commonly used acid-base indicator is phenolphthalein, which is colorless in acidic solutions and pink in basic solutions. Another popular indicator is litmus, which turns red in acidic solutions and blue in basic solutions. The choice of the best indicator depends on the specific experiment and the pH range being tested.
Which indicator is used in titration for strong acid?
For the titration of a strong acid, the indicator typically used is phenolphthalein. Phenolphthalein changes color in the pH range of 8.2 to 10, which is suitable for titrating a strong acid with a strong base to determine the equivalence point.
Which indicator is used in titration of oxalic acid with HCl?
Both HCl and oxalic acid are acids. Therefore, since there is no alkali present, these compounds do not undergo neutralization. So there is no suitable indicators for the addition of these two reagents.
What is used to determine the pH of an acid or base?
indicator
What are the names of plants that can be used as indicators of acid and alkali?
What are the names of plants that can be used as indicator of acid and alkali
What is the purpose of an acid base indicator?
An acid-base indicator is used to determine the pH of a solution by changing color at different pH levels. This visual change helps to identify whether a solution is acidic, basic, or neutral. It is commonly used in titrations and other chemical experiments to monitor the progress of a reaction.
What is phenalphaline?
Phenolphthalein is a chemical compound commonly used as an acid-base indicator in titrations. It is colorless in acidic solutions and pink in basic solutions. It has also been used in the past as a laxative but is no longer commonly used for that purpose due to safety concerns.
