Problem: Sodium chloride, NaCl, is a strong electrolyte, as is hydroiodic acid, HI. Write the chemical equations for what happens when these substances are added to water.

FREE Expert Solution

Establish the definition of a strong electrolyte and determine the reaction when NaCl and HI is dissolved in water.

Step 1. Recall the definition of a strong electrolytes

Strong electrolytes

  • Strong electrolyte is salts that completely dissociate. Strong acids and bases are strong electrolytes
  • Examples are strong acids like HCl, HBr, HI, HNO, H2SO4, HClO3 and HClO4
  • Strong bases where it is composed of OH-, H- or O2- paired with Group 1A and 2A (Ca, Sr, and Ba) metals.
  • Soluble ionic compounds are also considered strong electrolytes.
