PHYSICAL PROPERTIES OF ACIDS: 1. This chapter includes the Physio chemical properties of Amino acids.Before going to the physical and chemical properties of amino acids, we should brush back the amino acids basic points. Oleic and linoleic unsaturated fatty acids are widely distributed in plants. Turns red litmus blue. (More about pH value in the next sub-topic) Alkaline solutions turn red litmus paper blue. Properties of Acids and BasesChemistryAcids and BasesWhat Are Acids and Bases?Properties of Acids and BasesThe pH ScaleTitrationsBuffers It's frequently possible to tell acids and bases apart from one another by some of their easily observed chemical and physical properties. 3. The long chain length of fatty acid has a high melting point than short-chain fatty acids. Physical Properties of Fatty Acid: Saturated fatty acids are solid at room temperature. 5. Caustic alkalis (KOH, NaOH) are highly corrosive. Unsaturated fatty acids are liquid at room temperature. Properties of Fatty Acids and Fats: Physical Properties: 1. Acid solutions have pH values lesser than 7. They are insoluble in water. Amino acids are basically building blocks of proteins. That was a brief overview regarding acid properties. The most common examples of unsaturated fatty acids are mentioned in table. Physical Properties of Carboxylic Acids. So, here are the physical properties of acids : 1. Turns blue litmus red. Solutions of acids can turn blue litmus paper to red. Some physical and chemical properties of these compounds are discussed in this subsection. 4. Fats and fatty acids are soluble in organic solvents, such as petroleum ether, benzene and chloroform. Chemical Properties of Alkalis. There are many different properties of bases. Some of the characteristics of the most important acids are their physical properties, their strength and their ability to neutralize bases, among others. Physical Properties of Acids. Chemical Properties of Acids Chemical Properties of Bases 1) Acids to have a sour taste 2) Acids release H- ions 3) Acids have a pH below 7. Physical Properties of Acids Physical Properties of Bases; Sour in taste in aqueous solution; Mineral acids (HCl, HNO3, H2SO4) are highly corrosive. Acids are sour. Strong Acids Strong Bases Weak Acids Weak Bases Physical/Chemical Properties of Acids Physical/Chemical Properties of Bases Arrhenius Model Bronsted-Lowry Model Comparison Between Strong/Weak Acids/Bases Common Household Items PH and POH Explanation Buffers Acid… The solubility of fatty acids decrease due to increase in no. Most of the properties of carboxylic acids are a result of the presence of the carboxyl group. Phosphoric acid is also a weak acid and phosphoric acid uses include rust removal, acidifying food and beverages and as a pH adjuster in several cosmetics, among others. of the methylene group Acids, bases and their properties are a large domain of chemistry and there is much more detail involved that is provided here. Bitter in taste in aqueous solution. React with metal carbonates to produce salt carbon dioxide and water. Optical Isomerism: All amino acids, except glycine which has two H atoms on the α-carbon, have an asymmetric α-carbon (the 4 valence bonds are attached to different atoms or groups). Acids are water-soluble. Important Physical Properties of Amino Acids: 1. Properties of Carboxylic Acids. Physical Properties of Alkalis. 1. 2. Alkaline solutions have pH values greater than 7. There are four common reactions of alkalis: Acids have a SOUR taste 2. Alkalis have the following properties: Alkalis have bitter taste and a slippery soapy feel.
