Full Answer

Bases are substances that act as the opposite of acids; if acids are proton donors, bases are proton acceptors; if acids are electron pair acceptors, then bases are electron pair donors, etcetera. A reaction between a base and an acid is called neutralization, in which two liquid solutions (one base and one acid) combine and react to create a solution of salt and water.

Properties of bases include:

  • Bitter taste
  • Slippery to the touch
  • Change the color of indicators
  • Conduct electric current in liquid solution form

Common bases include detergents, soap, lye and household ammonia.

  • Q:

    What happens when an acid and a base are combined?

    A:

    Mixing a base with an acid results in a chemical reaction called neutralization. The result is a perfectly balanced solution of salt and water with a pH of 7 if the acid and base are balanced properly. Depending on the bases and acids used, it can be a dangerous experiment.

  • Q:

    Is KH2PO4 an acid or a base?

    A:

    Monopotassium phosphate, with the chemical formula KH2PO4 or H2KO4P, is neither a base nor an acid but a salt. A salt, usually in crystalline form, is produced via an acid-base chemical reaction. Monopotassium phosphate is the neutralized product of phosphoric acid and potassium hydroxide.

  • Q:

    What are some of the properties of acids?

    A:

    Some of the properties of acids are that they conduct electricity when they are dissolved in water, liberate hydrogen when they react with active metals and, when combined with a base, will produce a salt and a neutralized base. Acids also have a pH which is less than 7 in an aqueous solution, and will change the color of blue litmus paper to red. In an operational sense, acids increase the concentration of H+ ions when they are dissolved in water.

  • Q:

    What is a monoacidic base?

    A:

    According to Dictionary.com, a monoacidic base is a base that when dissolved in water produces one hydroxide ion or OH-, per molecule. In other words, a monoacidic base divides itself into two main components or molecules after reacting with water. One of the molecules is always a hydroxide ion and based on the definition of a monoacidic base, only one hydroxide ion is present.
