Answer

Brief Explanations:

  1. Acids taste sour, react with metals, and turn blue - litmus paper red. Bases taste bitter, feel slippery, and turn red - litmus paper blue.
  2. Acids produce hydrogen ions ($H^+$) in solution, while bases produce hydroxide ions ($OH^-$).
  3. Not always. pH depends on both acid strength and concentration. A very dilute strong - acid solution can have a higher pH than a concentrated weak - acid solution.
  4. The concentration of ions affects the conductivity, osmotic pressure, and chemical reactivity of solutions. For example, higher ion concentrations generally lead to higher electrical conductivity as there are more charge - carriers available.

Answer:

  1. Acids: Sour taste, react with metals, turn blue litmus red. Bases: Bitter taste, slippery feel, turn red litmus blue.
  2. Acids: Produce $H^+$ ions. Bases: Produce $OH^-$ ions.
  3. No. pH depends on concentration too. Dilute strong - acid can have higher pH than concentrated weak - acid.
  4. Affects conductivity, osmotic pressure, reactivity. Higher ion concentration, higher conductivity (more charge - carriers).
