Interpretation:
The number of units of Na+ and OH- produced when 1000 units of NaOH were dissolved in water needs to be determined.
Concept Introduction:
The substance which dissociated in water into charged particles i.e. ions is known as electrolytes.
Answer to Problem 20A
1000 units of Na+ ions and 1000 units of OH- ions will produce.
Explanation of Solution
Electrolytes are of two types:
Strong electrolytes
Weak electrolytes
The electrolytes which are completely ionized are known as strong electrolytes. Strong electrolytes have high electrical conductivity.
The ionized reaction of strong electrolyte is shown below:
The electrolytes which are partially ionized are known as weak electrolytes. Weak electrolytes have low electrical conductivity.
Sodium hydroxide is a strong electrolyte which conducts electricity. NaOH is an alkali water soluble strong base.
The reaction is shown below:
When NaOH dissolved in water it dissociates into Na+ and OH- ions it means when 1000 units of NaOH dissolved in water then 1000 units of Na+ ions and 1000 units of OH- ions will produce.
Thus, 1000 units of Na+ ions and 1000 units of OH- ions will be produced.
