Why are litmus paper and phenolphthlein particularly useful indicators for distinguishing between acids and bases?
Litmus paper changes color in acidic solutions (red) and basic solutions (blue), allowing for easy identification. Phenolphthalein is colorless in acids and pink in basic solutions, making it a reliable indicator for distinguishing between the two. These properties make them valuable tools for quickly determining the pH of a substance.

How indicators can tell the difference between acid and a base?
Indicators can differentiate between acids and bases based on their chemical properties. Indicators change color depending on the pH of the solution they are added to. For example, acids will turn indicators like litmus paper red, while bases turn them blue. This color change occurs because indicators respond to changes in hydrogen ion (H+) concentration in the solution.
What is difference between external and internal indicators used in titration?
Internal indicators that are used in titration exist in the titration reaction as either a reactant or a product. External indicators is added to the reaction mixture, but does not exist in the reaction.
What is the distinguishing test between primay secondary and tertiary amine?
The distinguishing test between primary, secondary, and tertiary amines is the Hinsberg test. In this test, the amine is reacted with benzene sulfonyl chloride. Primary amines produce insoluble precipitates, secondary amines form soluble products, and tertiary amines do not react.
Why testing with phenolphthalein would not show weather the solution is acidic or neutral?
Phenolphthalein changes color at a pH around 8.2 to 10, indicating alkalinity. Since it does not change color in acidic or neutral solutions, it is not suitable for distinguishing between acidic and neutral solutions. Other indicators like litmus paper would be more appropriate for that purpose.
What is a distinguishing characteristic of a saturated fatty acid-?
A distinguishing characteristic of a saturated fatty acid is that it contains only single bonds between carbon atoms, resulting in a straight molecular structure. This straight structure allows saturated fatty acids to pack tightly together, making them solid at room temperature.
A pelvic ultrasound can detect what types of pregnancy?
Ultrasound is particularly useful in distinguishing between intrauterine (within the uterus) and ectopic (outside the uterus) pregnancies.
What is distinguishing mean?
Distinguishing is simply means differences between some two things.
How does daltonism affect your eyes?
Daltonism, known as color blindness, affects the eyes by causing difficulty in distinguishing certain colors, particularly red and green. This is typically due to a genetic deficiency in the cones of the eye that are responsible for color vision. People with daltonism may see colors differently or have trouble distinguishing between specific hues.
What is the distinguishing feature of a brown spider with a black head?
