Use formula Common indicators * phenolphthalein * methyl orange ⸻ Русский Титрование используют для нахождения концентрации. Шаги: 1. Добавить индикатор 2. Медленно добавлять раствор 3. Смотреть изменение цвета ⸻ 14. Redox Reactions English Oxidation Loss of electrons Reduction Gain of electrons OIL RIG: * Oxidation Is Loss * Reduction Is Gain ⸻ Русский Окисление = потеря электронов Восстановление = получение электронов ⸻ 15. Hydrophobic and Hydrophilic English Hydrophobic “Water-fearing” Does not mix with water. Example: oil Hydrophilic “Water-loving” Mixes with water. Example: salt ⸻ Русский Hydrophobic: не смешивается с водой Hydrophilic: смешивается с водой ⸻ 16. Organic Chemistry Naming (IMPORTANT FOR TEST) English Alkane Only single bonds General formula: C_nH_{2n+2} Alkene Contains double bond General formula: C_nH_{2n} Alkyne Contains triple bond General formula: C_nH_{2n-2} ⸻ Русский Алкан: только одинарные связи Алкен: двойная связь Алкин: тройная связь ⸻ 17. IUPAC Naming Quick Rules English Step 1 Find longest chain. Step 2 Count carbons: * meth = 1 * eth = 2 * prop = 3 * but = 4 * pent = 5 * hex = 6 Step 3 Find double bond. Step 4 Number chain from nearest double bond. Step 5 Name branches: * methyl * ethyl ⸻ Русский 1. Найти самую длинную цепь 2. Посчитать углероды 3. Найти двойную связь 4. Нумеровать с ближайшей двойной связи 5. Назвать ответвления ⸻ 18. Combustion English Combustion = burning in oxygen. Example: C_5H_{12}+8O_2\rightarrow5CO_2+6H_2O Products: * carbon dioxide * water ⸻ Русский Горение — реакция с кислородом. Продукты: * CO₂ * H₂O ⸻ 19. Activity Series English More reactive metals replace less reactive metals. Mg is more reactive than H: → reacts with acid Cu is less reactive than Fe: → cannot replace Fe ⸻ Русский Более активный металл вытесняет менее активный
