6 Alkaline Acid According to Arrhenius
According To Arrhenius the year 1903 Acid is matter which in water will yield hydrogenic ions ( ion hidronium) causing can increase concentration of H3O? ( ion hidronium). Example : Alkaline is matter which in water will yield hydroxide ion causing can increase konsentasi OH? ( hydroxide ion) Hal.: 6 Isi dengan Judul Halaman Terkait

8 Alkaline Acid According To Bronsted Lowry
According To Bronsted-Lowry the year 1923 : Acid is a compound which can give proton ( H⁺) Alkaline is a compound standing as proton acceptor ( H⁺) Bronsted-Lowry tahun 1923 : Asam adalah suatu senyawa yang dapat memberikan proton (H?) Basa adalah suatu senyawa yang berperan sebagai penerima proton (H?) Reaction : Hal.: 8 Isi dengan Judul Halaman Terkait

9 Alkaline Acid According To Lewis
Acid is chemistry compound acting electron pairs receiver. Alkaline is chemistry compound acting electron pairs giver. Reaction : Hal.: 9 Isi dengan Judul Halaman Terkait

10 Alkaline Acid Strength
Degree of acidity ( pH) be concentration of ion H⁺ in a condensation Formula : pH = ₋log[H⁺] For pure water at temperature 25 ° C [H⁺]=[OH⁻]= 10⁻⁷ mole/litre So pure water pH = ? log10⁻⁷ = 7 On the basis of this understanding, obtained : if pH = 7 → condensation haves the character of neutral If pH < 7 → condensation haves the character of acid If pH > 7 → basic condensation At room temperature pKw = pH + pOH = 14 Hal.: 10 Isi dengan Judul Halaman Terkait

11 Condensation Of Buffer

15 Hydrolysis and Condensation pH of Salt
Ion ion dissolved in water can be grouped to become four kinds : Anion from acid strong : Cl⁻, NO₃⁻,SO₄²⁻ Anion from acid weak : CH₃COO⁻,CN⁻,HCO₃⁻,S²⁻ Cation from strong alkaline : Na⁺,K⁺,Mg²⁺ Cation from weak base : NH₄⁺,Ag⁺,Cu²⁺ Reaction of salting in general can be written down as follows HA MOH → MA + H₂O Acid alkaline salt water If a salt dissolved in water, there is two possibilities which can happened Ion ion coming from acid weak or coming from weak base will react with water. Reaction of ion with water called as hydrolysis Ion ion coming from acid strong or coming from strong alkaline doesn't react with water Hal.: 15 Isi dengan Judul Halaman Terkait

Continuation Salt salt can be grouped to become four types based on its(the acid and origin alkaline Acid coming from strong acid strong and alkaline, example NaCl,K₂SO₄,Ba(NO₃)₂ pH = 7 2. Acid coming from weak acid strong and alkaline, example CH₃COOK, Mg(CN)₂ pH = ½(14 + pKa + log M) 3. Acid coming from acid strong and weak alkaline, example (NH₄)₂SO₄, AgCl pH = ½(14 - pKb - log M) 4. Acid coming from acid weak and weak alkaline, example CH₃COONH₄, AgCN pH = ½(14 +pKa + pKb) Hal.: 16 Isi dengan Judul Halaman Terkait

17 Alkaline Acid Mixture pH
There is three possibilities which can happened, if we mix acid solution and alkaline solution : If miscible acid and alkaline nothing that its(the bersisa(semua is [used up/finished] reacts), hence formed is condensation of salt. Formula which we apply is condensation hydrogen ion exponent formula of salt ( hydrolysis) If there is rest of acid weak or rest of weak base, hence formed is condensation of buffer. Formula which we apply is condensation hydrogen ion exponent formula of buffer If there is rest of acid strong or rest of strong alkaline, hence formed is strong acid solution or strong alkaline solution. Formula which we apply is strong acid strong hydrogen ion exponent formula or alkaline hydrogen ion exponent Hal.: 17 Isi dengan Judul Halaman Terkait

18 Alkaline Acid Titration
Volumetric analysis is determination of concentration of a condensation by the way of reacting a number of the condensation volumes to a number of volume other condensation which its(the concentration have been known Volumetric analysis executed through a method so-called titration Titration formula : If konsentasi molarity V₁M₁ = V₂M₂ If concentration of normality V₁N₁ = V₂N₂ condensation of Indicator is condensation applied in titration to determine titration end point by experiencing discoloration Hal.: 18 Isi dengan Judul Halaman Terkait
