Q1. A green layer is gradually formed on a copper plate left exposed to air for a week in a  bathroom. What could this green substance be? 

Answer. It is due to the formation of basic copper carbonate [CuCO₃.Cu(OH)₂].


Q2. Why are elements of Group IA i.e. H, Li, Na, K, Cs and Fr called alkali metals?

Answer. Because oxides of these elements dissolve in water to give alkali or soluble hydroxides.  


Q3. A non-metal X exists in two different forms Y and Z. Y is the hardest natural substance,   whereas Z is a good conductor of electricity. Identify X, Y and Z. 

Answer. ‘X’ is carbon, ‘Y’ is diamond as it is the hardest natural substance and ‘Z’ is graphite as   it is good conductor of electricity.

Class 10 Physics - Electricity - Open Circuit vs Closed Circuit vs Short Circuit (#cbseClass10Physics)(#Class10Physics)(#eduvictors)


Open Circuit

An open circuit implies that the two points are externally disconnected, which is equivalent to a resistance R = ∞ . This means that theoretically no current(I = 0) can flow between the two terminals, regardless of any value of potential difference ( V= 0 to ∞).

Answer: Strength of acid and base can be estimated by using universal indicator.


Q2: What is a universal indicator?

Answer: Universal indicator is used to estimate the strength of an acid or a base. It is a mixture of several indicators. It shows different colours at different concentrations of H⁺ ions in the solution.


Q3: What is pH value of a solution?

Answer: The pH of a solution is inversely proportional to the concentration of hydrogen ions in it. Mathematically the pH of a solution is inversely proportional to the concentration of hydrogen ions in it. pH is a pure number, it has no units.
