INSTRUCTIONS TO CANDIDATE

A. GENERAL : 1. Please read the instructions given for each question carefully and mark the correct answers against the question

numbers on the answer sheet in the respective subjects. 2. The answer sheet, a machine readable Optical Mark Recognition (OMR) is provided separately. 3. Do not break the seal of the question-paper booklet before being instructed to do so by the invigilators. B. MARKING SCHEME : Each subject in this paper consists of following types of questions:- Section - I 4. Multiple choice questions with only one correct answer. 5 marks will be awarded for each correct answer and

–2 mark for each wrong answer. 5 Passage based single correct type questions. 3 marks will be awarded for each correct answer and –1 mark for each wrong

answer. Section - II 6. Column matching type questions (4 × 5 type). 8 marks will be awarded for the complete correctly matched answer and No

Negative marking for wrong answer. However, 2 marks will be given for a correctly marked answer in any row. Section - III

7. Numerical response (single digit integer answer) questions. 3 Marks will be awarded for each correct answer and no Negative marking for wrong answer. Answers in this section are to be given in the form of single integers i.e. 0 to 9.

C. FILLING THE OMR : 8. Fill your Name, Roll No., Batch, Course and Centre of Examination in the blocks of OMR sheet and darken circle properly. 9. Use only HB pencil or blue/black pen (avoid gel pen) for darking the bubbles. 10. While filling the bubbles please be careful about SECTIONS [i.e. Section-I (include single correct, reason type, multiple

correct answers), Section –II (column matching type), Section-III (include integer answer type)]

Section –I Section-II Section-III

For example if only 'A' choice is correct then, the correct method for filling the bubbles is

A B C D E

For example if only 'A & C' choices are correct then, the correct method for filling the bublles is

A B C D E

the wrong method for filling the bubble are

The answer of the questions in wrong or any other manner will be treated as wrong.

For example if Correct match for (A) is P; for (B) is R, S; for (C) is Q; for (D) is P, Q, S then the correct method for filling the bubbles is

P Q R S TA BCD

Ensure that all columns are filled. Answers, having blank column will be treated as incorrect. Insert leading zeros (s)

Passage # 2 (Ques. 10 to 12) Sodium sulphite (Na2SO3) is added to meat as a

preservative. The presence of Na2SO3 can be detected by adding dil. H2SO4 when the pungent smelling gas evolved turns the lime water milky. The gas evolved was detected as sulphur dioxide. The SO2 evolved was dissolved in water and it requires I2 solution in order to oxidize SO2 to –2

4SO

in titration. SO2 + 2H2O + I2 → 4H+ + –2

4SO + 2I–

In order to check the results of titration, excess barium chloride is added to the final solution. The resulting precipitate is collected and weighed.

Q.10 SO2 and CO2 both turns lime water milky. Which of the following reagent can be used to distinguish these two gases ?

(I) K2Cr2O7/H2SO4 (II) KMnO4/H+ (III) I2 solution (A) I, II, III correct (B) I, III only correct (C) II, III only correct (D) III only correct Q.11 SO2 gas is used as a bleaching agent. Its bleaching

action is : - (A) temporary and due to its oxidizing nature (B) temporary and due to its reducing action (C) permanent and due to its oxidizing action (D) permanent and due to its reducing action



Q.12 Which of the following compounds is formed, when Na2SO3 is boiled with sulphur.

(A) Na2SO4 (B) Na2S2O5

(C) Na2S2O6 (D) Na2S2O3

Section - II

This section contains 2 questions (Questions 1, 2). Each question contains statements given in two columns which have to be matched. Statements (A, B, C, D) in Column I have to be matched with statements (P, Q, R, S, T) in Column II. The answers to these questions have to be appropriately bubbled as illustrated in the following example. If the correct matches are A-P, A-S, A-T; B-Q, B-R; C-P, C-Q and D-S, D-T then the correctly bubbled 4 × 5 matrix should be as follows :

Section - II

This section contains 2 questions (Questions 1, 2).

Each question contains statements given in two

columns which have to be matched. Statements (A, B,

C, D) in Column I have to be matched with

statements (P, Q, R, S, T) in Column II. The answers

to these questions have to be appropriately bubbled

as illustrated in the following example. If the correct

matches are A-P, A-S, A-T; B-Q, B-R; C-P, C-Q and

D-S, D-T then the correctly bubbled 4 × 5 matrix

should be as follows :

A B C D

Mark your response in OMR sheet against the

question number of that question in section-II. + 8

marks will be given for complete correct answer (i.e.

+2 marks for each correct row) and NO NEGATIVE

MARKING for wrong answer.
