Acid Base Reactions :Acid Base Reactions


Slide 2:Acid Rain damage


Reaction Definition :Reaction Definition When two or more compounds or elements combine to produce a new substance with different physical and chemical properties.


Acid :Acid An acid is a chemical that donates Hydrogen ions to a reaction HCl + NaOH ? NaCl + HOH Acids react with metal to release Hydrogen gas Acids have a pH from 0 to 6.9 Acids Taste sour


Slide 5:Hydrochloric Acid HCl Sulfuric Acid H2SO4 Nitric Acid HNO3 Carbonic Acid H2CO3 Hydrofluoric Acid HF


Bases :Bases Bases are chemicals that donate OH hydroxide ions to a reaction Bases taste bitter Bases have a p.H. from 8 to 14


Slide 7:Saponifacation is the reaction of fats with bases to make soap


Slide 8:Sodium Hydroxide NaOH Potassium Hydroxide KOH Magnesium Hydroxide Mg(OH)2


p.H. :p.H. P.H. is a measure of the strength of an acid or base Acids 0-6.9 more H+ Neutral 7 (Pure Water) same number of H and OH Bases 8-14 More OH


Indicators :Indicators Indicators are chemicals that change colors in the presence of an acid or a base Phenolphthalein – red in p.H. of 8.2 or higher Universal Indicator p.H. 2-12


Neutralization Reactions :Neutralization Reactions When an acid and a base react they are both neutralized, turned into salt and water.


Slide 13:HCl + NaOH ? NaCl + H2O HCl + KOH ? KCl + H2O H2SO4 + NaOH ? NaSO4 + H2O + H2
