Homework Answer: Q26-Option 4:The Chemical Name of Prussic Acid is Hydrogen Cyanide(HCN). -HCN is a colourless, highly volatile and highly poisonous liquid. - The reactivity of HCN is very high. - IUPAC Name: Formonitrile. - Boiling Point: 26°C, Melting Point: -13.4° C. From Today's Session: Acids, Bases and Salts 1-Acids: Acids are the substance which have a sour taste and turns blue litmus to red. - Acids are good conductor of electricity in aqueous solution. - Pickels are always kept in glass jar because acid present in them reacts with metal to produce hydrogen gas. 2-Bases: Substances which have bitter taste ,soapy to touch and turns red litmus to blue. - Some Bases like NaOH, KOH etc are good conductor of electricity in aqueous solution and in molten state. - Base react with acid to give salt and water ,this reaction is called neutralization reaction because both neutralizes each other. 3- Salts: Salts are the product of neutralization reaction b/w acid and base. - pH is measure of acidity/ basicity. 4- Buffer Solutions: The Solution which resist any change in its pH value after adding a small amount of acid or base to it are buffer solutions. - Acidic Buffer Solutions: pH7. Thanks Sir for the Great Session👍👍
