CASE STUDY BASED QUESTIONS:

1. Read the following and answer the questions :

There are many substances which are used to detect the solutions as acidic or basic. They are called Acid-Base indicators. Depending upon the property of the indicator, we have different groups of Acid-Base indicators. Some indicators show different colors in acidic or basic medium and some indicators give different odors in acidic and basic medium. These indicators are either extracted from the plants or synthesized in the laboratory or industry.

Short answer type questions.

Question. With the help of an example explain what happens when a base reacts with a non- metallic oxide. What do you infer about the nature of non-metal oxide?
Answer : Oxides of non-metals react with bases to form salt and water. For example, the reaction between carbon dioxide and calcium hydroxide. Calcium
hydroxide, which is a base, reacts with carbon dioxide to produce salt and water.
       CO           +       Ca(OH)2 → CaCO3      +              H2O
Carbon dioxide           Calcium hydroxide          Calcium carbonate
Hence, oxides of non-metals are acidic in nature.

Question. When zinc metal is treated with a dilute solution of a strong acid, a gas is evolved. Name the gas evolved. Write the chemical equation of the reaction involved and also write a test to detect the gas formed.
Answer : Zinc metal gives hydrogen gas when it is treated with dilute sulphuric acid.
Therefore, the gas evolved is hydrogen.
Zn     +      H2SO4       →     ZnSO4       +      H2
zine       Sulphuric acid   zine sulphate       Hydrogen
Test for hydrogen gas: When a burning candle is brought near hydrogen gas, it burns with a pop sound which confirms the presence of hydrogen gas

Question. Fresh milk has pH of 6. When it changes to curd, will its pH value increase or decrease? Why?
Answer : When fresh milk changes to curd, the pH of the solution is likely to decrease. Actually, lactose present in milk gets converted to lactic acid when curd is formed from milk. Therefore, the medium becomes more acidic and its pH decreases.

 

Long answer type questions

Question. What will you observe when-
(i) Red litmus paper introduced into a solution of sodium carbonate.
(ii) A methyl orange drop is added to dilute hydrochloric acid.
(iii) A drop of phenolphthalein is added to the solution of lime water.
(iv) Blue litmus is introduced into a solution of Ferric chloride.
Answer : (i) The color of litmus paper will change to blue. Sodium carbonate dissolves in to water to form NaOH and Carbonic acid H2CO3. The solution is basic in nature since NaOH is a strong base and carbonic acid is a weak acid.
Na2CO3 + H2O -------→  2 NaOH + H2CO3
(ii) In the acidic solution, the color of methyl orange will change to reddish
(iii) Lime water contains traces of Calcium hydroxide Ca(OH)2 . It is therefore basic in nature. The colour of phenolphthalein will become pink.
(iv) Ferric chloride solution on reaction with water will form ferric hydroxide and HCl. Since the acid is strong, the solution will be acidic. Therefore the color of blue litmus will change to
red.
FeCl3 + H2O ----------→ Fe(OH)3+ 3HCl

Question. (a) Why does an aqueous solution of an acid conduct electricity?
(b) How does the concentration of hydrogen ion changes the solution of an acid is diluted with water?
(c ) Which has a higher pH value ; a concentrated or dilute HCl?
(d) What would you observe on adding dilute HCl to
(i) Sodium bicarbonate placed in a test tube.
(ii) Zinc metal in a test tube.
Answer : (a) An aqueous solution of an acid conducts electricity because in water an acid dissociates to give ions. Since current is carried by the movements of ions, a.q. solution of acid conduct electricity.
(b) Upon dilution, more of acid dissociates into ions Therefore concentration of hydrogen ion increases.
(c ) Although more H+ ions are formed upon dilution , but the number of ions per unit volume decrease. Therefore, pH will increase upon dilution.
(d) (i) CO2 gas would evolve accompanied by brisk effervescences.
NaHCO3 +HCl ------→ NaCl + CO2 + H2O
(ii) Hydrogen gas would evolve accompanied by brisk effervescences.
Zn + 2HCl ---→  ZnCl2 + H2

Question. Explain why:
(i) Common salt becomes sticky during the rainy season
(ii) Blue vitriol changes to white upon heating.
(iii) If bottle full of Conc. Sulphuric acid is left open in the atmosphere by accident, the acid starts flowing out of the bottle of its own.
Answer : (i) Common salt contains the impurity of MgCl2 which is of deliquescent in nature. When exposed to atmosphere, it becomes moist. Therefore common salt becomes sticky during the rainy season.
(ii) Blue vitriol (CuSO4.5H2O) upon heating changes to anhydrous copper sulphate which is white in color.
(iii) Concentrated Sulphuric acid is highly hygroscopic. It absorbs moisture from air and gets diluted. Since the volume increases, the acid starts flowing out of the bottle.

Question. (a) What is the action of red litmus on (i) dry ammonia gas (ii) solution of Ammonia gas.
(b) State the observation you would make on adding ammonium hydroxide to aqueous solution of (i) Ferrous Sulphate (ii) Aluminium Chloride.
Answer : (a) (i) Red litmus has no action on dry ammonia because it does not has hydroxyl ion.
(ii) When interact with ammonia solution it turns in blue as the solution has hydroxyl ion.
(b) (i) A green ppt of ferrous hydroxide will be formed
FeSO4 + 2 NH4OH -----→ Fe(OH)2 + (NH4)2SO4
(ii) A white ppt is formed
AlCl3 + 3 NH4OH ---→  Al(OH)3 + 3 NH4Cl

(c) How is sodium carbonate obtained from Sodium bi Carbonate?
Answer : (a) The raw materials used are: NaCl, Lime stone or CaCO3 and NH3
(b) NaHCO3 is sparingly soluble or less soluble in water and gets separated as a precipitate while NH4Cl remains in solution. The filtrate is removed by filtration.
