What will the pH of the following salt solution when salts made from strong acid and strong base and salt made from weak acid and strong base
Answers
In the case of strong acid and string base it will be neutral, means ph is about 7.
While in case of weak acid and string base it will basic in nature,means ph will be grater then 7.
Hope it will give you some idea.
Answer- The above question is from the chapter 'Acids, Bases and Salts'.
Acids: These are substances in which taste sour. They contain H⁺ ions.
Example: HCl, H₂SO₄, H₂CO₃, etc.
Strong acids have more H⁺ (aq) ions than weak acids.
Strong acids are HCl, H₂SO₄, HNO₃, etc.
Weak acids are H₂CO₃, H₃PO₄, etc.
Acids have pH less than 7.
Bases: These are substances in which taste bitter. They contain OH⁻ ions.
Example: KOH, NaOH, Ca(OH)₂, Mg(OH)₂ etc.
Strong bases have more OH⁻ (aq) ions than weak bases.
Strong bases are KOH, NaOH, Ca(OH)₂, etc.
Weak bases are Mg(OH)₂, NH₄OH, etc.
Bases have pH more than 7.
Question: What will the pH of the salt solution when salts made from strong acid and strong base and salt made from weak acid and strong base?
Answer: When salts are made from strong acid and strong base, they get neutralized to form a neutral salt and water.
This salt has pH = 7.
When salts are made from weak acid and strong base, they combine to form a basic salt and water.
This salt has pH more than 7.
