od question: 39
When iron(II)ohloride is dies- olved in water a pale-green sol- ution is obtained while iron(III) ohloride dissolves in water to give a yellowibh-brown solution,
a) What is reseposible
for the
::palexgreen colour of iron(II)
chloride solution? Do you
expect other iron(II) salts
to give solutions having sim ilar colour, if the salts are soluble?:
What is resposible for the yellowish-brown colour of iron (JIT)chloride? Do you think: the solutions of other iron (III) aalta also have this colourP
3. 0.628 g of iron powder was add- ed to. 50 cm of a hot 0 21 901- ution of iron(III) chloride. A few minutes later, the solution changes to pale-green, When

there is no further change ob- served, the iron powder remain- ing is washed with suitable agents, dried and weighed. is found to be 0.348 g.
a) Why a hot iron(III)chloride
solution is used?
b) What is the mess of iron powe
der used up by iron(III)chlo- ride solution?
How many moles of iron does: this mass represent?
d) How many jeoles' of iron(III)z
chloride are there in 50cm-
of 0.2M solution?
Write an equation for the re-.
action between iron(III) ions
and iron powder.
f) State which of the two, iron
powder or iron(III) ions, acte as an oxiddeing: agent? Explain your answer briefly.
C. It is often difficult to keep solution of iron(II) salts for long periods because they very often become yellow (due to the formation of iron(III) salts) easily.
What might be responsible for
this conversion?
b) From your discussion in (B),
suggest an easy way to stabi- lize solutions of iron(II) salts against such change. Question 40%

B. Three tubes contain aqueous. solutions of sodium salts “A, B and C respectively. When barium nitrate solution is add- ed to each of the tubes there da a white precipitate, On add− ing dilute. nitric acid the pre cipitates in tubes containing B and C respectively dissolve, giving gases D and E respect ively; the precipitate in the. tube containing A does not di ssolve at all, Gas D has a choking smell and decolourizes acidified potassium permangan- ate. Gaa E makes limewater cloudy.
Identify and name the subst- ances A, B, C, D and E.

B. Five labels have fallen off
bottles which were known to oon- tain aqueous solution of hydro- chloric sold, ammonium chloride, sodium chloride, calcium chlór- ide and sodium carbonate. All the solutions are colourless. A student was trying to restore the label properly and he did this by mixing solutions in pairs, denoting the contents of of the bottles by A, B, C, D and E. The results he had obtained were shown in the following.

1(a) Structure X is an iris.
(11)The size of the pupil
da adjusted by the out cle fibres in the iris. When the intensity of light is high, the cive cular muscle of the iris contracte while the radial muscle is relaxed so that the size of the pupil is reduced to allow less light entering the eye. When the light intensity is low, the radial muscle of the iria contracts while the circular muscle is relaxed so that the size of the pupil is larged to allow, more light entering the eye.
(iii) Pupil dilation is a
reflex. aotion, It cannot be adjusted conciously.
(iv) The functions of the
medulla oblongata are: 1. It is the centre for all involuntary movementa 2. It conducte impulses between the spinal cord and other parts of the brain.
3. It is the controlling centre of reflex actions. (b) The shoot tip shows the
response to the stimulus of the Light:

(ii) Auxins are produced in:
-the shoot tip and are able
to stimulate cell division. Since the shoot tips are illuminated on left side only, the auxin there is partly destroyed so that the auxin concentration de higher in the shaded: alde. Thus the shaded side grows more rapidly and the atem. curves towards light.

(d) A feed-back control
found in endocrine system.. For instance, if the thyroxin Level in the blood is low, the pitu- itary is stimulated to release thyrotrophin
which passes to the thy- roid in the blaod strean and stimulates the out- put of thyroxin. When the concentration of thyroxin is raised to the normal level, the: release of thyrotrophin ie decreased.
3.(a) R is a synapse. Trans-
mission of impulses can take place only in one direction through a bynapse.
(b) S contains cerebro-spinal
fluid. The fluid is for nutrition and protection of the nerve cells. It also give buoyance to the brain and spinal cord and pre- vents them from collapse.
(o) It is the grey matter of
the. cerebral cortex.
It is composed of the.
narve
bell-bodies.
The folding is to inor- ease the surface area of the gray matter which re- aults in increased com ordination and Localizat- ion of functions in the cerebral cortex.

p is a sensory neurone. Q Le a motor neurone . The sensory neurone carries impulses from re- ceptors to the apinal cord. The motor meurone carpies responge (from "the apinal
·cord or brain to the effecm tors.
(e) Spinal cord receives

This action is known as a reflex action caused by the spinal cord. The brain receives the stimulus. and notice the heat but does not involves itself in the action.
