Question

С чем реагирует K0H? И написать реакцию если реагирует. A)HCL B)CAO D)CO2 E)NAOH S)ZN(OH)2 G)H3PO4 T)BaCL2 J)Cu(NO3)2 L)CAC03

Answer 1

Ответ : А; D; S; G; T; J.

A) HCl+KOH = KCl+H2O
D) 2KOH+CO2 = K2CO3 + H2O
S)Zn(OH)2+2KOH =K2[Zn(OH)4] + 2H2O
G) H3PO4 + 3KOH = K3PO4+3H2O
T) BaCl2+2KOH = 2KCl + Ba(OH)2
J) Cu(NO3)2 + 2KOH = 2KNO3 + Cu(OH)2

Answer 2

Reactions of KOH with Various Substances

KOH, or potassium hydroxide, is a strong base that can react with various substances. Let's explore the reactions of KOH with the given substances:

A) HCl (hydrochloric acid): When KOH reacts with HCl, a neutralization reaction occurs, resulting in the formation of water (H2O) and potassium chloride (KCl): KOH + HCl → H2O + KCl B) CaO (calcium oxide): The reaction between KOH and CaO is a double displacement reaction, forming calcium hydroxide (Ca(OH)2): KOH + CaO → Ca(OH)2 C) CO2 (carbon dioxide): KOH can react with CO2 to form potassium carbonate (K2CO3): 2KOH + CO2 → K2CO3 + H2O D) NaOH (sodium hydroxide): KOH and NaOH are both strong bases, so they do not react with each other.

E) Zn(OH)2 (zinc hydroxide): When KOH reacts with Zn(OH)2, a double displacement reaction occurs, resulting in the formation of potassium zincate (K2ZnO2) and water (H2O): 2KOH + Zn(OH)2 → K2ZnO2 + 2H2O F) H3PO4 (phosphoric acid): The reaction between KOH and H3PO4 is a neutralization reaction, forming water (H2O) and potassium phosphate (K3PO4): 3KOH + H3PO4 → 3H2O + K3PO4 G) BaCl2 (barium chloride): When KOH reacts with BaCl2, a double displacement reaction occurs, resulting in the formation of barium hydroxide (Ba(OH)2) and potassium chloride (KCl): 2KOH + BaCl2 → Ba(OH)2 + 2KCl H) Cu(NO3)2 (copper(II) nitrate): The reaction between KOH and Cu(NO3)2 is a double displacement reaction, forming copper(II) hydroxide (Cu(OH)2) and potassium nitrate (KNO3): 2KOH + Cu(NO3)2 → Cu(OH)2 + 2KNO3 I) CaCO3 (calcium carbonate): KOH and CaCO3 do not react with each other.
