Acids Bases And Salts

Step 1: Understanding Electrolytes:
An electrolyte's strength is determined by its ability to conduct electricity, which depends on the presence of free, mobile ions.

Step 2: Comparing Dilute and Concentrated Acid:
Concentrated sulphuric acid is largely composed of molecules (H_2SO_4). Dilution with water causes the acid to ionize into H^+ and SO_4^2- ions.

Step 3: Linking Ionization to Conductivity:
Because dilute acid contains a significantly higher number of dissociated, mobile ions compared to the molecular form of concentrated acid, it conducts electricity much more effectively.

Step 4: Final Answer:
Both statements are true; the higher concentration of ions in the dilute form is exactly why it is a stronger electrolyte.
