What indicator is used for nh3?

If a chemical indicator is used—methyl orange would be a good choice in this case—it changes from its basic to its acidic color. Titration of a weak base with a strong acidA depiction of the pH change during a titration of HCl solution into an ammonia solution.

Which of the following indicators would be most possible to be suitable for the titration of nh3 with hno3?

The most suitable indicator for the titration is (c) alizarin yellow.

Which indicator can be used in the titration of h2so4 vs NaOH?

Phenolphthalein is an acid-base indicator that is colorless in acidic solutions and pink in basic solutions. If phenolphthalein is added to the original sample of sulfuric acid, the solution is colorless and will remain so while hydrogen ions are in excess.

What is a suitable indicator for titration?

The indicator phenolphthalein, whose range spans from pH 8 to 10, therefore makes a good choice for this type of titration. If you don’t know the pH change around the equivalence point of your titration, consult a general chemistry textbook.

Which of the following is the suitable indicator for h2so4 and nh4oh titration reaction?

Phenolphthalein is chosen for a strong acid – a strong base titration while methyl orange is suited for strong acid – weak base system.

Can universal indicator be used for titration?

The universal indicator is not used in titration because they have different pH ranges. It becomes difficult to determine the exact pH of the solution. Therefore, universal indicator is not used in titration.

What is the suitable indicator for strong acid and strong base?

phenolphthalein indicator
A strong acid- strong base titration is performed using a phenolphthalein indicator. Phenolphtalein is chosen because it changes color in a pH range between 8.3 – 10.

Which indicator is suitable for weak acid and strong base?

Phenolphthalein
Note: Phenolphthalein is used as an indicator for Strong acid -strong base titration. End point is color changes to fuchsia (light pink) color. Thymolphthalein is used as an indicator for weak acid and strong base.

What is a suitable indicator?

The suitable indicators for the following titrations are, (i) Strong acid Vs strong base: Phenolphthalein (pH range 8.3 to 10.5), methyl red (pH range 4.4 – 6.5) and methyl orange (pH range 3.2 to 4.5). (ii) Weak acid Vs strong base: Phenolphthalein. (iii) Strong acid Vs weak base: Methyl red and methyl orange.

What are the three types of indicator?

There are three types of economic indicators: leading, lagging and coincident. Leading indicators point to future changes in the economy. They are extremely useful for short-term predictions of economic developments because they usually change before the economy changes.
