Ans:Litmus paper may be used to distinguish between acids and bases. When a drop of solution is put to litmus paper, it turns red, indicating that it is an acid. If the litmus paper turns blue, it’s most likely a base. Q.3. What are the five properties of acids and bases? Ans:...
2) Acids can corrode (or eat away at) metals and skin. 3) Acids can be used as a reactant during electrolysis. 4) Acids will turn blue litmus paper red. What is a Base? A base (in chemistry) means having a pH (on the pH scale) of 8-14.It is a substance that can accept pr...
The characteristics of bases allow them to feel slippery in many instances and these compounds can typically conduct electricity. Litmus paper can be used to determine if a solution is basic as the litmus paper will change from red to blue in color. Answer and Explanation: ...
It is slower than litmus paper, it contaminates the solution, it does not tell about the acidic or basic strength, it requires more solutions than litmus paper, and if the solution is dark, the colour change is not visible.Q.3: How long does the red cabbage indicator last?Ans: Over ...
What does pH measure? How do these measurements vary between acids and bases?Differences between Bases and Acids:There are differences between acids and bases. Some of these differences are as follows: AcidBase Turns blue litmus paper to red Turns red litmus paper to blue. Prese...
Litmus, which is extracted from lichen, has purple color (see the image given below), but the condition is when it is neither acidic nor basic, i.e. neutral.Litmus basically is a plant belongs to Thallophyta, and in chemical experiment, it is commonly used as an indicator. The ...
The blue litmus paper remains blue when it comes in contact with a drop of dil. NaOH. Question 2: Explain why hydrogen gas is not collected by the downward displacement of air? Answer: Hydrogen gas is lighter than air and it will easily escape in the air. We cannot collect the lighter...
What is the litmus paper property of acids and bases ? Acids -red Bases- Blue What is the ph level of acids and bases? Acids- <7 Bases- >7 What is the PH of acid rain Lower than 5.6 What is the cause of acid rain Volcanic eruptions. Forest fires. Lightning bolts. What are the ...
Bases turn red litmus paper blue, have a bitter taste, and have a pH of greater than 7. Compare acid. 2. Mathematics a. The side or face of a geometric figure to which an altitude is or is thought to be drawn. The base can be, but is not always, the bottom part of the ...
Acids and bases react with each other in what is called aneutralizationreaction. The reaction produces salt and water and leaves the solution closer to a neutral pH than before. One common test of whether an unknown is an acid or a base is to wet litmus paper with it.Litmus paperis a ...
