Acids+and+Bases

== =//Whoever wrote this didn't state who they were. Add so you get credit!//= = Acids and Bases = PH: potential of hydrogen in a solution
 * describes the ions in a solution

__** Acids: **__ 0 - hydronium ions= (H2O+) 1 2 - pulls electrons away from others- metals 3 4 - tastes sour 5 6

__** Neutral: **__ OH + H3O = 2H2O -neutralization reaction

(alkali solutions) 8 - hydroxide ion = OH (unhappy) 9 10 11 - pull away hydrogens -organic materials 12 13 14 - taste= bitter and slippery
 * __ Bases: __**

Litmus paper- Old way to test pH solutions.

Universal Indicator- (new way) Paper that detects ions that are in solutions. Levels 1-13.

Hydrogen peroxide (H2O2)- acidic.

Saliva- Neutral, level 7.

Sometimes spicy foods are acidic, but not all the time.

Digestion


 * 1) Chewing= breaks down food .. increases reaction rate
 * 2) Stomach= HCI Acid breaks down food
 * 3) Intestinies=aborbs nutierents
 * 4) Colon= asborbs water
 * 5) Together ( Intestinies and Colon) are 25 feet long

Ways to detect if something is a Base or Acid What is Litmus paper?
 * 1) With a PH machine
 * 2) With Litmus paper
 * 3) Universial indicator
 * Litmus paper is paper and when you stick it in a liquid it tells you if it is a Acid or Base
 * If the paper turns Red its an Acid
 * If the paper turns Blue its a Base

Examples of acids:
 * Lemons - 2.3 pH
 * Hydrochloric acid - 0.1 pH
 * Sulphunic acid - 0.3 pH
 * Stomach juice - 1-3 pH
 * Vinegar - 2.9 pH
 * Apples - 3.1 pH
 * Oranges - 3.5 pH
 * Grapes - 4 pH
 * Sour Milk - 4.4 pH
 * White bread - 5.5 pH
 * Fresh milk - 6.5 pH

Examples of Bases:
 * Human Saliva - 6-7 pH
 * Distilled water - 7 pH
 * Blood Plasma - 7.4 pH
 * Eggs - 7.8 pH
 * Seawater - 7.9 pH
 * Borax - 9.2 pH
 * Milk of magnesia - 10.5 pH
 * Ammonia water - 11.6 pH
 * Limewater - 12.4 pH
 * Caustic soda - 14 pH

Facts about Bases :
 * another name for a base is Alkali
 * May have a soapy feel
 * can burn your skin
 * pH more than 7
 * found in shampoo
 * taste bitter
 * we use bases everyday

Facts about acids :
 * can burn your skin
 * sour taste
 * ph less than 7
 * dissolved in water .. the acid will give hydrogen ions
 * is a molecule

= = = Hi Everyone, = = So for our project this week we choos.... All about gum... = = = = I am really confused on if it would be an acid or base though.:( = = I am hoping one of you know the anwer?? = = Please write your answer below.... = = = = Thanks, = = Destiny Bach:) IT depends on the type of gum ...like bubble gum or mint gum :) = -brayden reis
