What is the solution of tin (II) chloride?
Solutions of tin (II) chloride can also serve simply as a source of Sn 2+ ions, which can form other tin (II) compounds via precipitation reactions. For example, reaction with sodium sulfide produces the brown/black tin (II) sulfide : SnCl 2 (aq) + Na 2 S (aq) → SnS (s) + 2 NaCl (aq)
How is tin formed?
An electric potential is applied, and tin metal is formed at the cathode via electrolysis . Tin (II) chloride is used as a mordant in textile dyeing because it gives brighter colours with some dyes e.g. cochineal. This mordant has also been used alone to increase the weight of silk.
What is the name of the compound that is a white crystalline solid?
Chemical compound. Tin (II) chloride, also known as stannous chloride, is a white crystalline solid with the formula Sn Cl 2. It forms a stable dihydrate, but aqueous solutions tend to undergo hydrolysis, particularly if hot.
What is tin used for?
Tin (II) chloride also finds wide use as a reducing agent.
Does tin chloride reduce silver?
This can be prevented by storing the solution over lumps of tin metal. There are many such cases where tin (II) chloride acts as a reducing agent, reducing silver and gold salts to the metal, and iron (III) salts to iron (II), for example: It also reduces copper (II) to copper (I).
Does tin chloride dissolve in water?
Tin (II) chloride can dissolve in less than its own mass of water without apparent decomposition, but as the solution is diluted, hydrolysis occurs to form an insoluble basic salt:
Is tin a Lewis acid?
Tin (II) chloride also behaves as a Lewis acid, forming complexes with ligands such as chloride ion, for example: SnCl 2 (aq) + CsCl (aq) → CsSnCl 3 (aq) Most of these complexes are pyramidal, and since complexes such as SnCl 3 have a full octet, there is little tendency to add more than one ligand.

Definitions of molecular mass, molecular weight, molar mass and molar weight
Molecular mass ( molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
How to calculate molecular mass?
Molecular mass (older name molecular weight) is the mass of a molecule calculated as the sum of the mass of each atom in the molecule multiplied by the number of atoms of that element in the molecule. Molecular mass is a dimensionless quantity numerically equal to the molar mass. Though molecular and atomic mass values are dimensionless, they are given the unit dalton (Da) or unified atomic mass unit (u), which is approximately the mass of a single proton or neutron and is numerically equivalent to 1 g/mol.
What is the mole of a substance?
All substances consist of atoms or molecules. In chemistry, it is important to measure their amounts accurately. The mole is used to express the amounts of reactants and products of chemical reactions. The mole, symbol mol, is the SI unit of the amount of substance. One mole contains exactly 6.02214076×10²³ elementary entities. This number is the fixed numerical value of the Avogadro constant, N A, when expressed in the unit mol⁻¹ and is called the Avogadro number. The amount of substance, symbol n, of a system is a measure of the number of specified elementary entities. An elementary entity may be an atom, a molecule, an ion, an electron, any other particle or specified group of particles.
What is the unit of mass?
The molar mass is a physical property, which is defined as the mass of a substance divided by its amount of substance in moles. In other words, it is the mass of one mole of a particular substance. In SI, the unit for molar mass is kg/mol. However, chemists almost always express molar masses in g/mol for convenience.
What is the name of the compound that is a tin?

What is the name of the hydrate of tin?
Several hydrates of tin tetrachloride are known. The pentahydrate, SnCl 4 ·5H 2 O was formerly known as butter of tin. They all consist of [SnCl 4 (H 2 O) 2] molecules together with varying amounts of water of crystallization. The additional water molecules link together the molecules of [SnCl 4 (H 2 O) 2] through hydrogen bonds. Although the pentahydrate is the most common hydrate, lower hydrates have also been characterised.
Overview
Chemical properties
Tin(II) chloride can dissolve in less than its own mass of water without apparent decomposition, but as the solution is diluted, hydrolysis occurs to form an insoluble basic salt:
SnCl2 (aq) + H2O (l) ⇌ Sn(OH)Cl (s) + HCl (aq)
Therefore, if clear solutions of tin(II) chloride are to be used, it must be dissolved in hydrochloric acid (typically of the same or greater molarity as the stannous chloride) to maintain the equilibrium towards …
Chemical structure
SnCl2 has a lone pair of electrons, such that the molecule in the gas phase is bent. In the solid state, crystalline SnCl2 forms chains linked via chloride bridges as shown. The dihydrate is also three-coordinate, with one water coordinated on to the tin, and a second water coordinated to the first. The main part of the molecule stacks into double layers in the crystal lattice, with the "second" wate…
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) + H2 (g)
The water then carefully evaporated from the acidic solution to produce crystals of SnCl2·2H2O. This dihydrate can be dehydrated to anhydrous using acetic anhydride.
Uses
A solution of tin(II) chloride containing a little hydrochloric acid is used for the tin-plating of steel, in order to make tin cans. An electric potential is applied, and tin metal is formed at the cathode via electrolysis.
Tin(II) chloride is used as a mordant in textile dyeing because it gives brighter colours with some dyes e.g. cochineal. This mordant has also been used alon…
