QuestionAnswer
litmus test solutions react chemically with paper -acids turn red on blue paper -bases turn bule on red paper
pH test paper solutions react chemically with the paper; color will indicate the level of acidity or alkalinity
acids and bases are ________ that seperate into ________ when disoloved in water 1.) ionic compounds 2.) ions
when both acids and bases disollve in water they... conduct electricity
tHE STRENGTH OF ELECTRICITY DEPENDS ON THE AMOUNT OF IONS
acids are acidic solutions
bases are alkiline solutions
Acid- taste sour, (examples are fruit juices and sodas,react with metals and other substances. They are corrosive and "eat away" at materials
Acids produce____ions when dissolved in water Hydrogyen (H+)
Bases- taste bitter and feel slippery, (examples:soaps and shampoos)bases do not react with metals in the same way. they can corrode with other substances
bases produce_____ when dissolved in water hydroxide (OH-)
when acids and bases mix they nuetralize!
Acid+base= water+ a "salt"

durring a chemical reaction matter cannot be created nor destroyed
an ionic bond is the attraction between Oppisitley charged ions
what is the total number of valence electrons an atom needs to become happy 8
the atomic number is the number of protons in the nucleus of an atom
when alkili metal in group 1 forms an ionic bond it loses one electron
an ionic bond must contain a metal and a nometal
an extremely reactive family; gains one valence electron when bonding halogen family(group 17)
an extremly reactive family ; each loses one valence electron when bonding Alkili metals(group one)
