What following statements about acids and bases is false?
Acids add H+ ions to a solution. Bases add OH- ions to a solution.
Is it true or false that strong acids turn universal indicator paper purple?
False. Universal indicator paper changes color based on the pH of a substance. Strong acids turn universal indicator paper red, orange, or yellow depending on the strength of the acid. Purple is not a color associated with strong acids on universal indicator paper.
True or false a safe way to identify a base is to feel it?
False. A safe way to identify a base is to use an indicator or pH paper to test the substance's pH level. Bases have a pH above 7 and can cause skin irritation or burns if touched directly.
True of false acids will turn blue litmus paper red?
True. Acids contain an excess of hydrogen ions (H+) that react with the indicator dye in blue litmus paper, causing it to turn red. This color change is a typical characteristic of acidic solutions.
Is it false that it a safe way to identify a base to feel it?
Yes, it is false. It's not safe to identify a base by touching or feeling it as some bases can cause skin irritation or burns. It's best to use indicators or pH strips to test for the presence of a base.

False. Universal indicator paper changes color based on the pH of a substance. Strong acids turn universal indicator paper red, orange, or yellow depending on the strength of the acid. Purple is not a color associated with strong acids on universal indicator paper.
Acid and neutral are opposites true or false?
False. Acids and bases can be said to be opposites.
True or false a safe way to identify a base is to feel it?
False. A safe way to identify a base is to use an indicator or pH paper to test the substance's pH level. Bases have a pH above 7 and can cause skin irritation or burns if touched directly.
Bases make a sour taste in your mouth true or false?
This is false. Bases are associated with bitter tastes and acids are sour. For an example, baking soda is a base and lemon juice is an acid.
When acids and bases react they form compounds called salt which are made of metals and nonmetals true or false?
Yes, it is correct.
An acid is typically a bitter-tasting slippery chemical compound?
Actually, acids are not typically bitter-tasting or slippery. Acids are characterized by their ability to donate protons, lower pH, and react with bases to form salts. Some common examples of acids include hydrochloric acid, sulfuric acid, and citric acid.
Is the use of a POA indicator is optional?
False
A median of a trapezoid is perpendicular to the bases true or false?
false. it is parellel to the bases
True of false acids will turn blue litmus paper red?
True. Acids contain an excess of hydrogen ions (H+) that react with the indicator dye in blue litmus paper, causing it to turn red. This color change is a typical characteristic of acidic solutions.

Yes, it is false. It's not safe to identify a base by touching or feeling it as some bases can cause skin irritation or burns. It's best to use indicators or pH strips to test for the presence of a base.
Acids are flammable true or flase?
False. Acids are not flammable; they do not burn or support combustion.
