rate of reactions/acids and bases Flashcards
what can change the rate of a reaction
higher temperature
higher concentration
smaller particle size
catalyst
how do u calculate the rate of a reaction
change in mass/ change in time
pH less than 7
acid
pH exactly 7
neutral
pH more than 7
alkaline
name three common lab acids
hydrochloric acid
sulfuric acid
nitric acid
name three common lab bases
lithium oxide
sodium hydroxide
calcium carbonate
acids and bases are chemical opposites that react together to form…
neutral substances
acid + metal oxide ~
salt + water
how do you name a salt
the first part comes from the metal and the second comes from the acid
what happens if you dilute an acid or alkali
the pH moves toward 7
what has more H+ than OH- ions
acidic
what has an equal concentration of H+ and OH- ions
neutral
what has more OH- ions than H+ ions
alkali
metal oxides in water =
alkaline solution
