Both (A) and (B)
Potassium metabisulphite, \(K_2S_2O_5,\) is a white crystalline solid with pungent odour of sulphur. It is used as an antimicrobial preservative, antioxidant and bleaching agent in food.
So, the correct answer is (D): Both (A) and (B)
Ans. K2S2O5 or potassium metabisulphite is a white crystalline solid with a strong sulfur scent.
Potassium metabisulfite (K2S2O5) is a chemical compound that is used as food preservatives. It is a white crystalline powder and has a sulphurous odour and it contains sulphur dioxide. This gives it antioxidant properties. The people may have an allergic response to the individual when they get the exposure to the products that contain potassium metabisulfite.
So, the correct answer is (D): Both (A) and (B)
Given below are two statements:
Statement I: D-(+)-glucose + D-(+)-fructose $\xrightarrow{H_2O}$ sucrose sucrose $\xrightarrow{\text{Hydrolysis}}$ D-(+)-glucose + D-(+)-fructose
Statement II: Invert sugar is formed during sucrose hydrolysis.
In the light of the above statements, choose the correct answer from the options given below -
Match the following:
What is the empirical formula of a compound containing 40% sulfur and 60% oxygen by mass?
The scientific study of matter’s properties and behaviour is known as chemistry. It is a natural science that studies the elements that makeup matter, as well as the compounds, made up of atoms, molecules, and ions: their composition, structure, qualities, and behaviour, as well as the changes that occur when they mix with other things.
