Electrolytic Conductance of Acids, Bases, and Salts
Chemistry ⇒ Acids, Bases, and Salts
Electrolytic Conductance of Acids, Bases, and Salts starts at 10 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Electrolytic Conductance of Acids, Bases, and Salts.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 10
A student adds a few drops of HCl to pure water and observes that the solution now conducts electricity. Explain why.
A student prepares two solutions: one of NaCl and one of glucose, both at the same concentration. Only the NaCl solution conducts electricity. Explain why.
Describe the difference between a strong electrolyte and a weak electrolyte.
Describe the effect of dilution on the conductance of a weak electrolyte.
Describe what happens to the conductance of a solution as the temperature increases.
Explain why a 0.1 M solution of NaCl conducts electricity better than a 0.1 M solution of CH3COOH.
Explain why distilled water does not conduct electricity, but tap water does.
Explain why molten salts conduct electricity but solid salts do not.
Explain why solid NaCl does not conduct electricity, but molten NaCl does.
Explain why sugar solution does not conduct electricity, but salt solution does.
Explain why the conductance of a solution decreases when the concentration of ions decreases.
Name one weak acid and one strong acid, and compare their conductance in aqueous solution.
The conductance of a 0.1 M NaCl solution is higher than that of a 0.1 M CH3COOH solution. Give a reason.
