Acid and Base
Q1. What is the definition of base and example?
Ans: Bases include sodium hydroxide, calcium carbonate, and potassium oxide. A base is a substance that can neutralize the acid by interacting with hydrogen ions. Ammonium hydroxide is a common example of a base because it is an acceptor of a proton (H+).
Q2. What is an acid and what are its properties?
Ans: Acids are ionic substances that produce positive hydrogen ions (H+) when dissolved in water. Acids have a sour flavor when dissolved in water, conduct electricity, and react with metals to form hydrogen gas. Litmus and other indicator chemicals can be used to identify acids. Acids cause blue litmus to become red.
Q3. What is the key difference between an acid and a base?
Ans: Acids and bases are two types of corrosive chemicals. Any item with a pH between 0 and 7 is considered acidic, while anything with a pH between 7 and 14 is considered base. Bases, on the other hand, are ionic substances that, when dissolved in water, form hydroxide ions (OH-).
Q4. How will litmus turn when an acid reacts with it?
Ans: Acids are known to turn blue with the litmus red.
Difference Between Acid and Base
Difference Between Acid and Base: Acid and Base are two very common terms in science and are used to differentiate between two large sets of compounds depending on their chemical behavior. Acids are chemical compounds that act as proton donors and can be easily recognized due to the possession of a releasable H+ ion. Bases are chemical compounds that act as proton acceptors and can be easily recognized in most cases, (inorganic bases) due to their possession of a releasable OH– ion. The main difference between acid and base is that acids act as proton donors whereas base act as proton acceptors. Upon the reaction of acids and bases in solutions, the H+ ions are neutralized by OH– ions, and they form water molecules together.
