Alkanes are saturated hydrocarbons. They contain only carbon-carbon and carbon-hydrogen single bonds. They are the least reactive of the organic compounds. The main source is crude oil. Hydrocarbon- a compound consisting only of hydrogen and carbon Saturated- Contain single carbon -carbon bonds only Unsaturated-contains a C=C bond Petroleum fraction- mixture of hydrocarbons with a similar chain length and boiling range The general formula for is CnH2n+2 (for ring alkanes is CnH2n)

WHY I CHOSE THE PROJECT? This project has been chosen in view of increasing demand of milk and also due to higher expectations of good quality and low fat diet requirements of the people with better awareness. Also the requirement for such quality products is more acute today. In this project I have prepared soy milk from soyabeans and have compared the conditions of formation of good quality cow milk yogurt and soy milk yogurt. I have also tried to find the effect of temperature on the pH of

pH In chemistry‚ pH is a measure of the acidity or basicity of an aqueous solution. Solutions with a pH less than 7 are said to be acidic and solutions with a pH greater than 7 are basic or alkaline. Pure water has a pH very close to 7. pH is defined as the decimal logarithm of the reciprocal of the hydrogen ion activity‚ aH+‚ in a solution. Universal indicator consists of a mixture of indicators such that there is a continuous color change from about pH 2 to pH 10. Universal indicator paper
