acids and bases

pure water is?

neutral

the ph scale

every change in the pH sale of one unit is change in 10 times the H+

acids

pH of 0-6.9

more H+ ions into a solution

litmus paper red

conduct electrity

eg. lemon juice, vingear, tomatoes

Bases

pH of 7.1 to 14

removes H+ions froma soltuion

eg baking soad, ovencleaner

acids in water

acuds releases H+ ions into solution

bases in water

bases remove H+ions from the solution

why is it important to maintain pH

good pH is 6-8

What can go wrong with an unbalanced pH?

Heart disease, weight gain, cancer, and diabetes

what is a buffer

basic solution, a buffer will realease H+ions

Acidic solution, a buffer will asorb H+ions

Bicarbonate buffer in the blood

Hemoglobin releases H+tions into the blood at the lunds

H+ joins with the bicarbonate ion to form H2CO3
