Acids and Bases By: Ruffa Mae T. Borbon Briar Rose Alexandria L. Pama III- Radon
Physical and Chemical behavior of Acids • 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.
Physical and Chemical behavior of Bases • 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.
Differences of Acids and Bases • 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.
Strength of Acids and Bases • 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.
How Acids and Bases are quantified • 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 • 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.
Common uses of Acids and Bases • 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.
