homework 2-chemical reactions Flashcards
What is an acid?
acids contain the element hydrogen with other non-metallic elements
What happens when an acid is mixed with water? *
hydrogen ions break away from the other elements to make the solution acidic
properties of an acid number 1
corrosive
POA 2 **
have a sour taste
POA 3 *****
turns blue litmus paper red
POA 4 ****
conducts electricity
POA 5 ****
reacts with some metals releasing hydrogen gas
what are strong acids
in a strong acid the hydrogen breaks away easily EG HCL is a strong acid bc the hydrogen atom breaks away from the chlorine
What are weak acids?
in an acid the hydrogen does not break away easily EG vinegar is a weak acid because the hydrogen does not break away .
what are bases?
In chemistry, a substance that can accept hydrogen ions in water and can neutralize an acid.
what do most bases do?
neutralize the acids
what happens when a base is mixed with water?
when a base is mixed with water the OH ions break away form the other elements or produced to make a solution basic.
e.g’s of bases 1
sodium hydroxide [caustic soda]
E.G 2
calcium hydroxide[lime]
E.G 3
ammonium hydroxide[cleaning ammonia]
