What are 3 common acids and bases?
Some Common Acids and Bases
- Acetic acid (CH3COOH): vinegar, acetate.
- Acetylsalicylic acid (HOOCC6H4OOCCH3): aspirin.
- Ascorbic acid (H2C6H6O6): vitamin C.
- Carbonic acid (H2CO3): soft drinks, seltzer water.

What taste do acids have?
Sour Taste
Acidic Foods have a Sour Taste – If you’ve ever tasted a lemon, you’ve had firsthand experience with the sour taste of acids. Citrus fruits, such as lemons, grapefruit, and oranges, all contain citric acid. Other foods such as vinegar and tomatoes also contain acids.
How do we test for acids?
There are two types of litmus paper: red litmus paper and blue litmus paper. Blue litmus paper turns red if the substance is acidic. Red litmus paper turns blue if the substance is basic or alkaline. Litmus turns red in acidic solutions and blue in basic solutions.
Are acids slippery?
Bases feel slippery, like soap, and acids just feel wet. You shouldn’t touch either because they can damage your skin.
Is ammonia a base?
Ammonia is a typical weak base. Ammonia itself obviously doesn’t contain hydroxide ions, but it reacts with water to produce ammonium ions and hydroxide ions. A weak base is one which doesn’t convert fully into hydroxide ions in solution.

What can you use to identify acids and bases?
– When you dip Blue litmus paper in a Acidic solution it turns to red color. – when you dip Red litmus paper in a Basic solution it turns to blue color. – In case where you don’t know whether the given solution is Acid/Base then use Neutral Litmus Paper which is basically Purple in Color, on exposure to acidic solution it give
What are the seven strong acids and bases?
Hydrochloric acid (denoted by the chemical formula HCl)
Which are acids and which are bases?
Acids and bases are two types of corrosive substances. Any substance with a pH value between 0 up to 7 is considered acidic, whereas a pH value of 7 to 14 is a base. Acids are ionic compounds that break apart in water to form a hydrogen ion (H+). Ionic compounds are a compound with a positive or negative charge.
What are some hazards of acids and bases?
Concentrated acids and bases are corrosive and can cause burns in contact with a human.
