Baking powder is a dry chemical leavening agent, a mixture of a carbonate or bicarbonate and a weak acid.The base and acid are prevented from reacting prematurely by the inclusion of a buffer such as cornstarch.Baking powder is used to increase the volume and lighten the texture of baked goods. 6. Question 4 State uses of bleaching powder? It is also, used in soda - acid fire extinguishers. But once a liquid is added, carbon dioxide gas is produced immediately. Since this reaction leads to the formation of soap, it is called the Saponification process. The soap molecule has two parts: a polar group (-COO-Na +) and a non-polar group (R-hydrocarbon part). Write the common name of CaOCl2. Baking powder is, quite simply, a pre-packaged version of bicarbonate of soda and cream of tartar which, when added to batters, will make them rise. Explain the function of each ingredient. 2 answers. Resources and materials to support your teaching of chemistry to primary, secondary and higher education students. Then you should go to the site: Joy of Baking and describe how Chemically Baking powder and Baking soda differ, and how they make cookies and cakes rise. Chemistry and Baking. Uses of the Bleaching powder : 1) Bleaching powder is also used in the paper industry . Write the chemical reaction taking place when the powder is heated during baking. Name its main ingredients. State one condition necessary to ensure the complete combustion of a fuel in air. Test if it’s still good by mixing ½ t baking powder with a little water. This includes safe and reliable practical experiments, interactive simulations, games and problem solving activities 2) Bleaching powder is commonly used for bleaching clothes. Students will be able to plan and carry out an investigation to compare the amount of gas produced in reactions between baking soda and baking powder when vinegar is added. Baking powder, on the other hand, also contains and acidic compound (commonly cream of tartar, potassium bitartrate) which helps break down the bicarbonate once mixed into the dough. If it foams, it’s good to use. If you have a yeast-free recipe, any fluffiness in the final biscuit is usually due to carbon dioxide formed from baking powder. The chemical leavening agent is essentially baking powder: a blend of a dried acid (for example cream of tartar and sodium aluminium sulphate) … 3) Bleaching powder is used to disinfect drinking water.

The standard enthalpy change deltaH for the thermal decomposition of silver nitrate according to the following equation is 78.67kj: AgNO3(s) yeilds AgNO2(s)+ 1/2O2(g) The standard enthalpy of formation of AgNO3(s) is -123.02kJ/mol. Baking powder is a chemical leavening agent that combines sodium bicarbonate (baking soda) and an acid (or even two acids!) NaHCO3 + H --(heat)-- CO2 + H2O + sodium salt tartaric acid When CO 2 gas is passed through lime water it forms calcium carbonate (CaCO 3 ), which is slightly soluble in water making it milky. Baking powder on heating produces carbon dioxide gas which causes bread or cake to rise making it soft and spongy. It is prepared by passing chlorine gas through dry slaked lime. The reaction between baking soda (sodium bicarbonate) and vinegar (dilute acetic acid) generates carbon dioxide gas, which is used in chemical volcanoes and other projects.Here is a look at the reaction between baking soda and vinegar and the equation for the reaction. The acid in baking powder is in the form of a salt, so it won’t react with the baking soda until a liquid is added.
