.Which of the following statements is/are false: a. A solution of sulphuric acid or hydrochloric acid in water conducts electricity. b. The materials that do not allow electric current to pass through them are called poor conductors of electricity. c. A solution of copper sulphate or sodium chloride in water will not conduct electricity.
Answers
Answer:
Explanation:
A. True
Hydrochloric acid , Sulphuric acid and Nitric acid etc. Note : Mineral acids are strong acids and these are completely ionised in water. One of the property of acids are : Acid solution are electrolyte,i.e., they conduct electricity : As acids produce the hydrogen ion when dissolve in water.
2. Partially correct more accurateluy can be insulators.
Materials which do not allow electricity to flow or pass through it , are called insulators or poor conductors of electricity. Insulators generally have low electrical conductivity. Wood, rubber, plastics are examples of insulator
3. True.
Solid copper sulphate does not conduct electricity, but when it is dissolved in water, it does conduct electricity. ... It does not have moblie or free electrons in its lattice structure to conduct electricity as in the case of other ionic comppunds ex. NaCl too.
Answer:
answer is C)
Explanation:
a) true as acids conducts electricity
b) true
c) false because copper sulphate and sodium chloride solution will conduct electricity and is used to electroplate iron etc
