Question

Given below are two statements: 
Statement (I): \(\textit{An element in the extreme left of the periodic table forms acidic oxides.}\) 
Statement (II):\( \textit{Acid is formed during the reaction between water and oxide of a reactive element present in the extreme right of the periodic table.} In the light of the above statements, choose the correct answer from the options given below:\)

• A. Both Statement I and Statement II are false
• B. Statement I is true but Statement II is false
• C. Statement I is false but Statement II is true
• D. Both Statement I and Statement II are true

Hint:

Elements on the left side of the periodic table form basic oxides, while elements on the right side, particularly non-metals, form acidic oxides when reacting with water.

Answer 1

The Correct Option is C

To assess the accuracy of the provided statements, it is necessary to comprehend the chemical properties of oxides formed by elements according to their periodic table positions.

1. Statement I: "An element located at the far left of the periodic table produces acidic oxides."
   • Elements at the extreme left of the periodic table are predominantly metals in groups 1 and 2 (e.g., alkali and alkaline earth metals). These metals characteristically form basic oxides, not acidic ones.
   • Conversely, elements at the extreme right of the periodic table (non-metals) typically form acidic oxides. Consequently, Statement I is inaccurate.
2. Statement II: "Acid is generated when water reacts with the oxide of a highly reactive element situated at the far right of the periodic table."
   • Elements at the far right of the periodic table are non-metals and generally form acidic oxides.
   • For instance, sulfur dioxide (\( \text{SO}_2 \)) reacts with water to yield sulfurous acid (\( \text{H}_2\text{SO}_3 \)), and carbon dioxide (\( \text{CO}_2 \)) reacts with water to produce carbonic acid (\( \text{H}_2\text{CO}_3 \)). This observation validates Statement II as true.

Based on this analysis, the conclusion is: Statement I is false, while Statement II is true.
