What does SnCl2 reduce?

Aromatic nitro compounds are readily reduced by SnCl2, 2 H2O in alcohol or ethyl acetate or by anhydrous SnCl2 in alcohol where other reducible or acid sensitive groups such as aldehyde, ketone, ester, cyano, halogen and O-benzyl remain unaffected.

What is stannous chloride in food?

Stannous chloride dihydrate (E512) is used as a food additive to provide colour retention and act as a antioxidant. It is, however, only permitted as an additive in one food category. The maximum permitted level (MPL) for stannous chloride is unchanged at 25 mg Sn/Kg body weight per day.

Why should we remove excess stannous chloride?

After the ferric ion is reduced by stannous chloride, the excess of stannous chloride is back-titrated with a potassium iodate solution using starch as indicator. Therefore it is necessary that potencies of stannous chloride solution is frequently standardized by the potassium iodate solution.

What is the chemical name for SnCl2?

Is iron chloride a gas?

Iron(II) chloride, also known as ferrous chloride, is the chemical compound of formula FeCl2. It is a paramagnetic solid with a high melting point. The compound is white, but typical samples are often off-white.

What is the role of SnCl2?

SnCl2 is widely used as a reducing agent (in acid solution), and in electrolytic baths for tin-plating. Tin(II) chloride should not be confused with the other chloride of tin; tin(IV) chloride or stannic chloride (SnCl4).

Can NO2 be reduced?

The best method for reduction of NO2 to NH2 is to use H2 /Pt in acetic acid. This gives the clean reaction product.

What is E512?

Stannous Chloride Dihydrate approved again for use as a food additive (E512) Stannous chloride dihydrate (E512) is used as a food additive to provide colour retention and act as a antioxidant. It is, however, only permitted as an additive in one food category.

What is the formula for stannous chloride ( II )?

From Wikipedia, the free encyclopedia 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. SnCl 2 is widely used as a reducing agent (in acid solution), and in electrolytic baths for tin-plating.

Which is the correct formula for tin ( II ) chloride?

How to make stannous chloride in a conical flask?

Add potassium sodium tartrate in the amount of 5 g into the conical flask. To the resulting solution, add a cold saturated solution of NaHCO3. Keep adding the cold saturated solution until the resultant solution in the conical flask becomes alkaline.

What kind of applications can stannous chloride be used for?

Stannous Chloride Uses As a strong reducing agent – The most common application for such a use would involve silvering of mirrors, where the precious metal is deposited on the glass to give way to the reflective surface. The equation is as follows: Sn2+ (aq) + 2Ag+ ➝ Sn4+ (aq) + 2Ag (s)
