A milkman adds a very small amount of baking soda to fresh milk.
Why does this milk take a long time to set as curd?

A milkman adds a very small amount of baking soda to fresh milk. why does he shift the ph of the fresh milk from 6 to slightly alkaline?

During summer season, a milkman usually adds a very small amount of baking soda to fresh milk. Give one reasons.

Packet milk does not get spoiled for longer time, why?

How does addition of small amount of curd to fresh milk,help formation of curd ? Mention a nutritional quality that get added to the curd.

Choose the correct set of True/Fasle for following statements: (i) Silver chloride is more soluble in very concentrated sodium chloride solution than in pure water. (ii) The pH of a buffer solution does not change on addition of small amount of an acid or a base. (iii) Addition of NH_(4)Cl does not affect the pH of a solution of NH_(4)OH (iv) Degree of hydrolysis of ammonium acetate does not depend upon the concentration of ammonium acetate solution. (v) A mixture of acetic acid and sodium acetate can act as buffer solution.

A colloidal solution is a type of mixture which consists of particles whose size varies between 1 and 1000 nanometres. In colloidal solution the particles are distributed evenly. During this process the particles do not settle down. This is one of the best know thing about colloidal solutions. Properties of colloids and their variation are a well-known area ever since the primitive age. The best example to prove their familiarity with us is that we know from very early times that coagulation of milk results in the formation of curd. Physical properties of colloids 1. The nature of the colloidal solution is heterogeneous i.e. unlike. These solutions dwell with two different phases : • Dispersed medium Dispersed phase. 2. Despite the fact that colloidal dispersions are unlike in description (nature), yet the dispersed fragments are not detectable by the human eye. This is due to the microscopic size of the particles in the solution. 3. The colour of the colloidal dispersion is determined by particles in the solution based on their size. The wavelengths of light that is absorbed will be longer ifthe size of the particle is large. 4. As a result of its size, the colloidal fragments can easily be passed through a traditional filter paper. However, these particles can be filtered by using membranes such as animal, cellophane, and ultrafilters. What are colloidal solution particle.
