-indicator turns red
-compound that increases hydronium ions when dissolved in water
-acid= "sour"(in latin)
-hydrogen ions give acid special properties
-sour taste
-many are corrosive
-most are poisonous
-acidic: containing acid
-conduct electricity; dissolves in water, ions form allowing solution to conduct electricity
-reactive with metal, gives off hydrogen gas
-sulfric acid= most widely used chemical i world; used in paper, paint, detergent, car batteries, etc.
-other types of acid= citric acid(fruits), nitric acid(fertilizers, rubber, plastic), hydrochloric acid(cleans swimming pools, digest foods in stomach, separate metal from other materials), ascorbic acid(vitamin c), acetic acid(found in vinegar), carbonic acid and phosphoric acid(used in soft drinks
-strength of acid depends on number of hydrogen ions formed when dissolved in water; the more ions formed, the stronger the acid is]]> 2017-02-10 04:40:13 UTC https://padlet.com/115544/twxmzld5g1tt/wish/152971615 115544 https://padlet.com/115544/twxmzld5g1tt/wish/152972500 -pH higher than 7
-indicator turns blue
-compound that makes many hydroxide ions when dissolved in water
-hydroxide ions give base special properties
-bitter taste & slippery feel
-many are corrosive
-if you get base on fingers(fingers with feel slippery), rinse hands with water and alert teacher
-conduct electricity; hydroxide ions form when base dissolves in water making solution a good conductor
-sodium hydroxide used in soap, paper, oven cleaners, products which help unclog drains, etc.
-ammonia used in household cleaners and fertilizers
-antacids help treat heart burn(reacts with acid in stomach, neutralizing excess acid)
-strength of base depends on number of hydroxide ions formed when dissolved in water; the more ions formed, the stronger the base is

-pure water has exact pH of 7
-formed when number of hydronium and hydroxide ions is balanced
-purple on litmus paper
-green on pH scale
-neutralize= cancel out acidity
-not corrosive, no electric conductivity
-neutralization reaction forms water and a salt
-water and salt are neutrals
-salt: ionic compound; formed when positive ions from base and negative ions from acid combine
-salts used to preserve food, melt snow/ice on roads/sidewalks, make wallboard for buildings, make lye and baking soda, etc.
-cooking oil and our own blood are also examples of neutrals]]> 2017-02-10 05:23:37 UTC https://padlet.com/115544/twxmzld5g1tt/wish/152973272 115544 https://padlet.com/115544/twxmzld5g1tt/wish/152973807 -pH scale used to describe acidity or basicity
-indicates= shows presence of acid
-litmus paper= type of indicator; contains litmus and comes in blue or red
-bromthymol blue= type of indicator; turns yellow when in contact with acid; turns darker blue when in contact with a base
-pH must be steady to keep environment healthy and balanced
-concentration= amount of acid or base dissolved in water]]> 2017-02-10 05:39:39 UTC https://padlet.com/115544/twxmzld5g1tt/wish/152973807 115544 https://padlet.com/115544/twxmzld5g1tt/wish/152974389 Indicator- compound that changes color in presence of acids or bases
Neutralization Reaction- reaction of an acid and base to form neutral solution(water and a salt)
pH- value used to describe acidity or basicity of a solution
Salt- ionic compound formed when metal atom replaces hydrogen of an acid
