 Acids release a hydrogen ion into water solution.  Acids neutralize bases in a neutralization reaction.  Acids corrodes active metals.  Acids turn blue litmus to red.  Acids donate protons.

 Bases releases hydroxide ion into water solution.  Bases neutralize acids in a neutralization reaction.  Bases denatures protein.  Bases turn red litmus to blue.  Bases accept protons.

 Acids › A solution that has an excess of H+ ions. › It tastes sour.  Bases › a solution that has an excess of OH- ions. › It tastes bitter. › Slippery to touch.

 The strength of an acid or base depends upon the concentration of ionized hydrogen.  A completely ionized acid or base is classified as a strong acid and strong base.  An incompletely ionized acid or base is classified as a weak acid and weak base.

 Acids and Bases are quantified through: › Solubility  Acids and bases depends on solubility because less soluble substances has a high pH and more soluble substances has a low pH. › Dissociation  a general process in which ionic compound separate or split into smaller particles, ions, or radicals, usually in a reversible manner.

 pH indicators are chemical compounds which are added in small amounts to a solution so that the pH of an acid or base can be indicated.  The pH scale measures how acidic or basic a substance is.

 Acids › Acids can be found on citrus fruits which provide citric acid that gives the fruits a sour taste. It is also found in the stomach which is gastric acid that the stomach secretes which grinds the food.  Bases › Baking soda, an example of a base, is commonly used in cooking and medical purposes. In the field of medicine, it acts as an antacid taken orally to treat acid indigestion and heartburn. Another example of a base is ammonia which can be used as household cleaners, particularly glass.
