See them allWhat happens when zinc granules are added to dilute hydrochloric acid? Write the chemical equation.
Answer
When zinc granules are added to dilute HCl, hydrogen gas is evolved with effervescence (bubbling). The reaction is: Zn(s) + 2HCl(aq) → ZnCl₂(aq) + H₂(g). This can be tested by bringing a burning candl…
Why does dry HCl gas not change the color of blue litmus paper, but HCl solution does?
Answer
Dry HCl gas does not produce H⁺ ions, so it shows no acidic properties. Only when HCl dissolves in water does it ionize: HCl + H₂O → H₃O⁺ + Cl⁻. The H₃O⁺ (hydronium) ions are responsible for acidic pr…
What happens when sodium carbonate reacts with hydrochloric acid? Give the test for the gas evolved.
Answer
Na₂CO₃(s) + 2HCl(aq) → 2NaCl(aq) + H₂O(l) + CO₂(g). Carbon dioxide gas is evolved. Test: Pass the gas through lime water [Ca(OH)₂]. Lime water turns milky due to formation of CaCO₃ precipitate: Ca(OH)…
Define neutralization reaction with an example and explain what happens at the ionic level.
Answer
Neutralization is the reaction between an acid and base to form salt and water. Example: NaOH(aq) + HCl(aq) → NaCl(aq) + H₂O(l). At ionic level: H⁺(aq) + OH⁻(aq) → H₂O(l). The H⁺ ions from acid combin…
What is pH scale? What does a pH of 7, less than 7, and greater than 7 indicate?
Answer
pH scale measures hydrogen ion concentration in solution, ranging from 0-14. pH 7 = neutral (pure water), pH < 7 = acidic (higher H⁺ concentration), pH > 7 = basic/alkaline (higher OH⁻ concentration).
Why is it recommended to use baking soda for bee sting relief?
Answer
Bee sting contains formic acid (methanoic acid) which causes pain and irritation. Baking soda (NaHCO₃) is mildly basic and neutralizes the acid: NaHCO₃ + HCOOH → HCOONa + H₂O + CO₂. This neutralizatio…
What is the chlor-alkali process? Write the chemical equation and name the three products formed.
Answer
Chlor-alkali process is electrolysis of brine (aqueous NaCl) to produce three useful chemicals. Equation: 2NaCl(aq) + 2H₂O(l) → 2NaOH(aq) + Cl₂(g) + H₂(g). Products: 1) Sodium hydroxide (caustic soda)…
Explain why our stomach produces HCl and what happens during indigestion.
Answer
Stomach produces HCl to: 1) Activate pepsinogen to pepsin enzyme, 2) Kill harmful bacteria, 3) Aid protein digestion, 4) Maintain acidic pH (~1.5-2). During indigestion, excess acid production causes …
