ScienceAn acidic gas has no effect on dry blue litmus but turns moist blue litmus red. Why?Class 10Chemical Substances – Nature and BehaviourAcids, Bases, and SaltsLevel 15MediumScienceAmong two acids of equal concentration, the first is a better conductor of electricity. Based on this, what can the first acid be like?Class 10Chemical Substances – Nature and BehaviourAcids, Bases, and SaltsLevel 13MediumScienceIf an acid is less electrically conducting than another acid of the same concentration, what is the most appropriate conclusion?Class 10Chemical Substances – Nature and BehaviourAcids, Bases, and SaltsLevel 11HardScienceWhich statement correctly explains the difference between a strong base and a concentrated base?Class 10Chemical Substances – Nature and BehaviourAcids, Bases, and SaltsLevel 10MediumScienceA student passes dry hydrogen chloride over dry blue litmus and observes no change. The same gas turns moist blue litmus red. What is the correct reason?Class 10Chemical Substances – Nature and BehaviourAcids, Bases, and SaltsLevel 10HardScienceA student says a concentrated acid and a strong acid are the same. What is the correct evaluation?Class 10Chemical Substances – Nature and BehaviourAcids, Bases, and SaltsLevel 9MediumScienceWhich option correctly gives an example of a strong acid and a weak acid?Class 10Chemical Substances – Nature and BehaviourAcids, Bases, and SaltsLevel 9HardScienceAn aqueous acid solution conducts electricity, but the pure acid conducts poorly. What does this observation support?Class 10Chemical Substances – Nature and BehaviourAcids, Bases, and SaltsLevel 8MediumScienceTwo acids have the same concentration. The first acid is a good conductor of electricity and the second is a weak conductor.
