Question

Какие из веществ формулы которых приведены реагируют с гидроксидом калия а)SO2 , б)Ca,в)HCI,г)NaOH,д)CuSO3?

Answer 1

а)SO2,в)HCI,д)CuSO3.........................................

Answer 2

Reactivity with Potassium Hydroxide

а) SO2: Sulfur dioxide (SO2) reacts with potassium hydroxide (KOH) to form potassium sulfite and water. ``` SO2 + 2KOH → K2SO3 + H2O ```

б) Ca: Calcium (Ca) reacts with potassium hydroxide (KOH) to form calcium hydroxide and potassium. ``` Ca + 2KOH → Ca(OH)2 + 2K ```

в) HCl: Hydrochloric acid (HCl) reacts with potassium hydroxide (KOH) to form potassium chloride and water. ``` HCl + KOH → KCl + H2O ```

г) NaOH: Sodium hydroxide (NaOH) does not react with potassium hydroxide (KOH) as they are both strong bases and do not undergo a neutralization reaction with each other.

д) CuSO3: Copper(II) sulfite (CuSO3) does not have a direct reaction with potassium hydroxide (KOH) in the provided search results.

In summary, sulfur dioxide, calcium, and hydrochloric acid can react with potassium hydroxide, while sodium hydroxide does not react with potassium hydroxide, and copper(II) sulfite does not have a direct reaction with potassium hydroxide.
