What is the structure of sncl2
What shape is SnCl2?
trigonal pyramidal shape
The structure of SnCl2 is a trigonal pyramidal shape or we can say that V shape is due to the presence of a lone pair of electrons based on VSEPR theory.
What is the Lewis structure of SnCl2?
What type of bond is SnCl2?
SnCl2 is ionic but SnCl4 is covalent.
How SnCl2 is formed?
Preparation. Anhydrous SnCl2 is prepared by the action of dry hydrogen chloride gas on tin metal. The dihydrate is made by a similar reaction, using hydrochloric acid: Sn (s) + 2 HCl (aq) → SnCl2 (aq) + H 2 (g)
What is the Lewis structure of sf6?

What is the meaning of sncl2?
Definition of stannous chloride
: a compound SnCl2 obtained by the action of chlorine, hydrogen chloride or hydrochloric acid on tin either as an anhydrous solid or a crystalline dihydrate and used chiefly in tinning and as a reducing agent and catalyst. — called also tin dichloride.
What is the molar mass of sncl2?
How do you make a sncl2 solution?
Procedure— Dissolve 1.0 g of Stannous Chloride in 2 mL of a mixture of 1 volume of nitric acid and 3 volumes of hydrochloric acid. Heat the solution on a water bath until nitrous vapor is no longer evolved. Dissolve the residue in water, and dilute with water to 25 mL.
Why SnCl2 is a strong reducing agent?
â—Ź SnCl2 acts as reducing agent because –
SnCl2 readily reacts with other compounds & get converted to stable SnCl4. During the reaction, SnCl2 gets oxidised while other compound is reduced. Thus, SnCl2 is a good reducing agent.
Is sncl2 soluble?
Yes SnCl2*2H20 is soluble in water, in less than its own weight of water, but it forms an insoluble basic salt with excess water making it soluble in ethanol.
Is sncl2 stable?
Sncl2 is more stable than sncl4. According, to the rule more charge has higher tendency to polarise the surrounding atom which tends to introduce a covalent character in molecule. sncl4 tends to have higher positive charge and its size is smaller. Hence, sncl4 is covelant and sncl2 is iocnic and stable.
Is SnCl2 a reducing agent?
Stannous chloride (SnCl2) is frequently used in nuclear medicine as a reducing agent to label many radiopharmaceutical products with technetium-99m (99mTc).
Will tin reduce iron?
Tin(II) ions also reduce iron(III) ions to iron(II) ions: tin(II) chloride reduces iron(III) chloride to iron(II) chloride in solution. In the process, the tin(II) ions are oxidized to the more stable tin(IV) ions.
Why is Sn 2 reduced?
Inert pair effect is less prominent in Sn than in Pb. Therefore, +2 oxidation of Sn is less stable than its +4 oxidation state. In other words, Sn2+ can easily lose two electrons to form Sn4+ and hence Sn2+ acts as a reducing agent.
Which is the best reducing agent?
Due to the smallest standard reduction potential, lithium is the strongest reduction agent. It decreases another substance when something is oxidized, becoming a reduction agent. Lithium is, therefore, the most powerful reducing agent.
What is meant by inert pair effect?
The inert-pair effect is the tendency of the two electrons in the outermost atomic s-orbital to remain unshared in compounds of post-transition metals.
Which is a better reducing agent SnCl2 or pbcl2 Why?
Since Pb is more down the group than Sn, it’s stable with +2 oxidation state where Sn can exhibit both +2&+4 but +4 is more stable due to which SnCl2 is a strong reducing agent.
Which is strongest oxidizing agent?
Elemental fluorine
Elemental fluorine, for example, is the strongest common oxidizing agent.
