Question
Assuming equal concentrations, rank these solutions by pH.
Highest pH to Lowest pH: HClO4(aq), Sr(OH)2(aq), NH3(aq), KOH(aq), HF(aq).
Answer “Assuming equal concentrations, rank these solutions by pH. HClO4 ”.
Strength of the Electrolyte & pH:
On the basis of their strength, electrolytes are divided into weak and stronger.
Strong electrolytes dissociate completely in water and weak electrolytes dissociate only partially.
The pH scale can range from 0 to 14.
Bases have a pH value greater than 7, acids have pH values smaller than 7, while neutral salts have pH values of 7.
The pH of an acid is smaller than that of a base. However, it will be stronger and more acidic.
Answer:
HClO4 is a strong acid so its pH is smallest.
HF is strong acid but it is not strong than HClO4
Sr(OH)2 is a strong base so its pH is highest.
KOH is strong base but it is not strong than Sr(OH)2
NH3 is a weak base.
Highest pH to Lowest pH:
Sr(OH)2(aq) > KOH (aq) > NH3(aq) > HF (aq) > HClO4(aq)
