Caustic alkalis (KOH, NaOH) are highly corrosive. (More about pH value in the next sub-topic) Alkaline solutions turn red litmus paper blue. There are four common reactions of alkalis: Turns blue litmus red. Some of the characteristics of the most important acids are their physical properties, their strength and their ability to neutralize bases, among others. So, here are the physical properties of acids : 1. Alkaline solutions have pH values greater than 7. Unsaturated fatty acids are liquid at room temperature. Oleic and linoleic unsaturated fatty acids are widely distributed in plants. Physical Properties of Fatty Acid: Saturated fatty acids are solid at room temperature. The most common examples of unsaturated fatty acids are mentioned in table. Properties of Carboxylic Acids. Physical Properties of Carboxylic Acids. Chemical Properties of Acids Chemical Properties of Bases Fats and fatty acids are soluble in organic solvents, such as petroleum ether, benzene and chloroform. Properties of Fatty Acids and Fats: Physical Properties: 1. Chemical Properties of Alkalis. 2. 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. Alkalis have the following properties: Alkalis have bitter taste and a slippery soapy feel. Most of the properties of carboxylic acids are a result of the presence of the carboxyl group. They are insoluble in 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). 5. 1. Physical Properties of Acids. Acids are water-soluble. PHYSICAL PROPERTIES OF ACIDS: 1. Some physical and chemical properties of these compounds are discussed in this subsection. 1) Acids to have a sour taste 2) Acids release H- ions 3) Acids have a pH below 7. of the methylene group 4. The solubility of fatty acids decrease due to increase in no. Acid solutions have pH values lesser than 7. React with metal carbonates to produce salt carbon dioxide and water. Physical Properties of Acids Physical Properties of Bases; Sour in taste in aqueous solution; Mineral acids (HCl, HNO3, H2SO4) are highly corrosive. Acids have a SOUR taste 2. The long chain length of fatty acid has a high melting point than short-chain fatty acids. That was a brief overview regarding acid properties. 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. Amino acids are basically building blocks of proteins. 3. There are many different properties of bases. Bitter in taste in aqueous solution. Important Physical Properties of Amino Acids: 1. 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… Acids are sour. Physical Properties of Alkalis. Turns red litmus blue. Solutions of acids can turn blue litmus paper to red. 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.
