Acids
taste sour (don't taste them!)...
the word 'acid' comes from the Latin acere, which means 'sour'acids are corrosiveacids change litmus (a blue vegetable dye) from blue to redtheir aqueous (water)
solutions conduct electric current (are electrolytes)react with bases to form salts and water evolve hydrogen gas (H2) upon reaction with an active metal (such as alkali metals, alkaline earth metals, zinc, aluminum)
Bases
taste bitter (don't taste them!)
feel slippery or soapy (don't arbitrarily touch them!)
bases don't change the color of litmus;
they can turn red (acidified) litmus back to bluetheir aqueous (water) solutions conduct an electric current (are electrolytes)react with acids to form salts and water

thanks bro
class do you read
*Acids are ionic compounds ( a compound with a positive or negative charge) that break apart in water to form a hydrogen ion (H+).
*The strength of an acid is based on the concentration of H+ ions in the solution. The more H+ the stronger the acid.
Example: HCl (Hydrochloric acid) in water
*The strength of an acid is based on the concentration of H+ ions in the solution. The more H+ the stronger the acid.

*Bases are ionic compounds that break apart to form a negatively charged hydroxide ion (OH-) in water.
*The strength of a base is determined by the concentration of Hydroxide ions (OH-). The greater the concentration of OH- ions the stronger the base.
Example: NaOH (Sodium Hydroxide-a strong base) in water
