Which one of the following is acidic?
Correct answer: A. B(OH)3
- A. B(OH)3
- B. Ca(OH)2
- C. Mg(OH)2
- D. NaOH
Explanation
Boron hydroxide, B(OH)3, is an acidic compound. It exhibits acidic properties due to the presence of the boron atom, which has an electron-deficient nature and can accept electron pairs from water molecules, forming hydronium ions (H3O+) and making the solution acidic.The other options, Ca(OH)2, Mg(OH)2, and NaOH, are all basic or alkaline compounds.

About Periodic Properties and Trends
Periodic properties arise from electron configuration and effective nuclear charge, producing trends in atomic and ionic radius, ionization energy, electron affinity, electronegativity, metallic character and reactivity. Comparisons run across periods and down groups, with attention to common exceptions. The topic also relates these trends to the behavior of s-block and p-block elements.
