about acid-base

1. CHEMISTRY ACID-BASE

2. Acid-base theorm Arhennius Bronsted-lowry lewis

3. ARHENNIUS THEORM Acid is a subtance that can produce ions H+ Base is a subtance that can produce ions OH-

4. Bronsted-lowrytheorm Acid is a subtance that can give proton H+ to other subtance.(proton donor) Base is a subtance that can accept the proton H+ from other subtance. (proton acceptor)

5. Reaction: AcidH+ + base conjugate BaseOH- + acid conjugate Definition: Acid conjugate: bases that have received 1 ion H+ Base conjugate: acid that have 1 ion released 1 ion H+

6. For example: ACID BASE CONJUGATE ACID CONJUGATE BASE

7. Lewis theorm Acid is a subtance that can accept lone pair electron from other subtance Base is a subtance that can donate the lone pair electron to other subtance and merge into one.

8. charateristic ACID Sour taste Corrosive Blue litmus to be red It can react with metal, and produce salt and H2 Ionozide to be ion hydrogen positive , ion acid negative It can react with carbonat and produce water(H2O),salt, and CO2 Can react with base subtance and will produce salt and water(H2O) BASE Bitter taste Feels slippery Red litmus to be blue Ionozide to be ion metal positive and ion hidrocsile negative Can react with acid Can react with salt

9. Characteristic Strong acid In group seventh A(VII A) For example: HI,HCl,HClO4,HNO3

10. Weak acid For example: HF,H2S,HCN And there’s COO ! For example: CH3COOH

11. Strong base Can found in group of IA,IIA,and IIIA IALi,Na,K,Rb,Cs IIACa,Sr,Ba IIIAAl

12. Weak base For example: NH4OH

13. The potential of hydrogen(pH) BASIC FORMULA:

14. Addition: If the charateristic of the subtance are same, for example base subtance with subtance base ! (this formula just use for two subtance or more that have same charateristic) Just info: (OH-) is the concentration of base subtance, you can change it by (H+)

15. The formula to determine the concentration. JUST INFO: (H+)=CONCENTRATION OF HYDROGEN IN ACID SUBTANCE (OH-)=CONCENTRATION OF OH- IN BASE SUBTANCE K= IONIZATION CONSTANT ALPHA=DEGREE OF IONIZATION a=ACID b=BASE

16. DETERMINE pH and pOH Kw= water equilibrium constant

17. Ok, we’re finish!! So, you have known what is acid and base! And you’ve known how to determine pH or potential of hydrogen! Ms.Reny reezarschool.blogspot.com
