Question

Al(OH)2,Cu(ОН)2 это какие оксиды, и как их различить?

Answer 1

Это гидроксиды или основания
1. Амфотерный гидроксид алюминия (так как Ал это Амфотерный металл
2 Нерастворимый гидроксид меди (см таблицу растворимости)

Answer 2

Это не оксиды, а основания. Называются гидроксид алюминия и гидроксид меди. Различить предельно легко. Гидроксид алюминия содержит алюминий, а гидроксид меди содержит медь.

Answer 3

Al(OH)2 and Cu(OH)2: Types of Oxides and How to Differentiate Them

Al(OH)2 and Cu(OH)2 are not oxides; they are hydroxides. Hydroxides are compounds containing the hydroxide ion, OH-. They are formed when a metal reacts with water or an acid to produce a base.

Al(OH)2: - Aluminum hydroxide, Al(OH)3, is an amphoteric hydroxide, meaning it can act as both an acid and a base. It is commonly used as an antacid to relieve symptoms of heartburn, acid indigestion, and upset stomach.

Cu(OH)2: - Copper(II) hydroxide, Cu(OH)2, is a blue solid that is sparingly soluble in water. It is used as a fungicide, particularly to control downy mildew in vines, vegetables, and ornamentals.

Differentiating Al(OH)2 and Cu(OH)2: - One way to differentiate between Al(OH)2 and Cu(OH)2 is through their chemical properties and uses. Aluminum hydroxide is commonly used as an antacid, while copper(II) hydroxide is used as a fungicide.

Citations: - Source mentions "2 Al(OH)3 + 3 CO2" and "2 ZnSO4 + 2 Na2CO3 + H2O = 2 Na2SO4 + Zn2(OH)2CO3 + CO2," indicating the chemical properties of aluminum hydroxide and its reactions. - Source states "Cu(NO3)2 + 2KOH = Cu(OH)2 + 2KNO3," which highlights the chemical properties of copper(II) hydroxide.
