Experiment

2. is a substance that releases a positively charged
hydrogen ion, H, in water.
Acid H+ + Negatif ion
 Acid divided by 2 :
1. Organik Acid
2. Anorganik Acid
 Characteristic of Acid :
 Possess Sour taste
 Characteristric of Corosive
 Redden litmus paper.
 Can react with metal.
 Produce Hydrogen

3.  Properties of Acids
 Acids are easily recognized by their sour taste.
 Citric acid makes lemons and limes taste sour.
 Vinegar is sour because it contains acetic acid.
 However, you should never test any material in the
laboratory by tasting it.
 A way to test for acids is to use litmus paper.
 Litmus paper contains a compound that changes color
in acids and bases.
 Acids turn blue litmus paper red.

4.  Table Acid which recognizably :
Name Acid Be Found In
1. Carbonat Acid Carbonat drink
2. Sulphuric Acid Battery car,Fertilizer
3. Citric Acid Orange
4. Nitrate Acid Fertilizer, Explosive
 Table Element Acid and Chemistry Formula :
Name Element Acid Chemistry Formula
Carbonat Acid H2CO3
Sulphuric Acid H2SO4
Nitrate Acid HNO3

5.  A base is a substance that produces hydroxide
ions when dissolved in water. The formula for a
hydroxide ion is OH.
Base Positif ion + OH
 Characteristic of Acid :
 Possess Bitter taste
 Slippery
 Blueing litmus paper
 Can spoil skin

6.  Properties of Bases
 Like acids, bases have a common set of properties. In
aqueous solutions, they feel slippery on your skin.
 You experience this when you use soap, which contains a
base.
 If you have ever gotten soap in your mouth, you know how
bitter it tastes.
 A bitter taste is another physical property of bases.
 Solutions of bases cause red litmus paper to turn blue.
 Like solutions of acids, solutions of bases contain ions, so
they are electrolytes.
 Bases neutralize acids by forming salts and water.

7.  Table Base which recognizably :
Name Base Be Found In Chemistry Formula
1. Aluminium Hydroksida Deodorant,Antasid KOH
2. Calcium Hydroksida Mortar,Plaster NaOH
3. Magnesium Hydroksida Antasid Al(OH)3
4. Natrium Hydroksida Matterb soap Mg(OH)2

8.  Saltconstitute chemical substances that
usually the shape solid crystal and shaped by
means of react netralisation between
element acid and element base.
 React between acid and base are react
neutralization.
Acid + Base Salt + Water
For Example :
 HCI + NaOH NaCI + H2O

9.  Besides produce from react between acid and
base.Salt also could produce from reaction
others,namely :
1. Base + Oxide Acid Salt + Water
2. Acid + Oxide Base Salt + Water
3. Oxide Acid + Oxide Base Salt
4. Metal + Acid Salt + Hydrogen
 Some Example Salt and Purpose :
Name Salt Formula Purpose
NaCI Nitrogen Cloride Kitchen Salt
KNO3 Calium Nitrate Matter Fertilizer
NaF Natrium Fluoride Toothpaste
CaSO4 Calcium Sulphuric Matter Gypsum

10. is a substance that releases a positively
charged hydrogen ion, H, in water.
Acid H+ + Negatif ion
 A base is a substance that produces hydroxide
ions when dissolved in water. The formula for a
hydroxide ion is OH.
Base Positif ion + OH

11.  Salt constitute chemical substances that usually
the shape solid crystal and shaped by means of
react netralisation between element acid and
element base.
 React between acid and base are react
neutralization.
Acid + Base Salt + Water
