Q1
State whether sait solution is acidic, basic or neutral. How will you confirm it ?
Answers
Answer:
A pH less than 7 indicates an acidic solution, a pH greater than 7 indicates a basic solution, and a pH of 7 indicates a neutral solution. Determining whether a salt exhibits acidic or basic character, then, requires dissolving the salt in water and measuring the pH of the resulting solution.
Explanation:
Look , salts are generally neutral but sometimes they can be acidic or basic .
Now if we want to know if its acidic or basic , the most fundamental approach to it is look for the H or OH ions in the salt .
Consider the possibility of salt without any OH ions . If you get a neutral salt (when you remove any OH ions ) then the salt you had was basic .
Same is for acidic salt . Just replace the H ion .
What happens actually is , in a neutralisation reaction the OH ions of base are unable to completely react with the H ions of an acid .This results in the formation of a salt with excess of H ions or OH ions and hence the salt is termed as Acidic or Basic respectively !
