It is used in textile industry for bleaching cotton and linen Plaster of Paris (Calcium Sulphate Hemihydrate – CaSO 41/2 H 2 O): It is used for plastering bones; It is used for making casts for statues Question 5 Sulphuric acid is called King of Chemicals Why is it called so? Answer:Besides all conventional components used in common plastering mortars,cement, lime, sand, and/or industrial fillers, and different kinds of additions (resins, fibers, cellulose deviants, and others) the trial mortars involved the use of PCMNumerical Analysis of the Energy Improvement of It is used in plastering of fractured bone, in making toys, decoration materials and rough surfaces smooth Uses of POP is based on the fact that on mixing with water it changes to gypsum and sets into hard solid mass Soaps are sodium or potassium salts of long chain fatty acids Saponification:RBSE Class 10 Science Notes Chapter 5 Chemistry in Bondaid for plastering Almost all surface applied bonding agents are compounded from polyvinyl acetate emulsions These waterbased adhesives are very safe to use because they are nontoxic, nonhazardous and nonflammableDifferent Types of Construction Chemicals Constro 221 Water used for mixing and curing shall be clean, reasonably clear and free from objectionable quantities of silt, oils, alkalis, acids, salts so as not to weaken mortar 222 Water tested shall be in accordance with IS 3025 Maximum permissible limits of deleterious materials in water as given in IS 4562000PARTICULAR SPECIFICATION PLASTERING WORK

It is used for plastering bones; It is used for making casts for statues; Question 5 Sulphuric acid is called King of Chemicals Why is it called so? Answer: Sulphuric acid is called King of Chemicals because it is used in the preparation of many Other compounds It is used in car batteries also Acids react with metallic oxides to give salt and water this it features a broad application range as it is mostly used in plastering but also in special applications such as sealing mud and concrete The dosages lie between 0,05 % and 0,6 % LIGAPHOB N 91 Reactive hydrophobing agent based on unsaturated fatty acids This product development was driven by application technology and economical aspectsPETER GREVEN Your partner for building protectionPlaster of Paris (CaSO4 1/2 H2O): Chemically, Plaster of Paris is calcium sulphate hemihydrate It is called Plaster of Paris because it is obtained from gypsum which is mainly found in Paris Preparation : Plaster of Paris is obtained by heating gypsum (CaSO 4 2H 2 O) at 373 K in a kilnProperties and Uses of Plaster of Paris Chemistry Calcium oxide is widely used as a building material It is an important constituent of portland cement (which is obtained by roasting limestone and sand with clay) Its large quantities are used in the steel industry, where it is used as a flux to remove P, S, and Si It is also used as a lubricant in steel wire drawing and in neutralising wastesCalcium (Ca): Properties Uses – StudiousGuyPlaster of Paris is Calcium Sulphate Hemihydrate This is obtained when Calcium Sulphate is heated at 100C Calcium Sulphate is also called Gypsum This was easily available and abundant in Paris, where it was used for plastering Hence the nameWhy P O P is called Plaster Of Paris I mean What is the
