MnS (Manganese Sulphide) and CuI (Copper Idodide) will also dissolve in dilte \(HNO_3\) but not in\(H_2O\)

Manganese sulfid I agree, but copper-I-iodide I disagree. Do you have a proof for it?

Cuprous Iodide + Nitric Acid = Copper(I) Nitrate + Hydrogen Iodide
\(CuI + HNO_3 \rightleftharpoons CuNO3 + HI\)
is a Double Displacement (Metathesis) reaction where one mole of Cuprous Iodide [CuI] and one mole of Nitric Acid [HNO3] react to form one mole of Copper(I) Nitrate [CuNO3] and one mole of Hydrogen Iodide [HI]
Cuprous Iodide + Nitric Acid = Diiodine + Nitrate Radical + Copper Hydride
\(2CuI + 2HNO_3 \rightleftharpoons I_2 +2NO_3 + 2CuH\)
Two moles of Cuprous Iodide [CuI] and two moles of Nitric Acid [HNO3] react to form one mole of Diiodine [I2], two moles of Nitrate Radical [NO3] and two moles of Copper Hydride [CuH]

Re: Predict which of the following compound will dissolve in the diluted HNO₃ but not in H₂O
Do you use AI, because there is some bullshit in. NO3 radical under this circumstances and CuH is not existing. Or do you have a link where I can find it.
If CuH would be there your sample would be a small bomb.

I am sorry. CuI will not dissolve in dilute \(HNO_3\)
Copper(I) iodide (CuI) is **almost insoluble** in water¹. Its solubility in water is extremely low, only about **0.000042 g/100 mL** at 25°C¹. However, it can dissolve in the presence of sodium iodide (\(NaI\)) or potassium iodide (\(KI\)) to form the linear complex anion \([CuI_2]^-\)¹³. It's also soluble in liquid ammonia, dilute hydrochloric acid, potassium cyanide, or sodium thiosulfate solution².

Re: Predict which of the following compound will dissolve in the diluted HNO₃ but not in H₂O
There not useful, because its redoxreaction which takes place with conc. HNO3. In the question it was told diluted HNO3.
Dont use this things, if you dont have knowledge what realy goes on.

Re: Predict which of the following compound will dissolve in the diluted HNO₃ but not in H₂O
Author said \(MgF2\) not \(CuI\) will dissolve in dilute \(HNO_3\) but not in \(H_2O\). You didn't say \(MgF_2 , MnS\) will also dissolve in dilute \(HNO_3\) but not in \(H_2O\)
Yes, both \(MgF_2\) and \(MnS\) contain anions of weak acids.
- \(MgF_2\) contains the fluoride ion (\(F^-\)) which is the conjugate base of hydrofluoric acid (\(HF\)), a weak acid¹².
- \(MnS\) contains the sulfide ion (\(S^2-\)) which is the conjugate base of hydrogen sulfide (\(H_2S\)), also a weak acid⁶⁸.
Remember, the conjugate base of a weak acid can act as a weak base. So, in the presence of a strong acid, these anions can accept protons and form their corresponding weak acids. For example, the sulfide ions from MnS can combine with hydrogen ions from a strong acid like HCl to form a weak acid \(H_2S\)⁶. Similarly, fluoride ions from \(MgF_2\) can combine with hydrogen ions to form hydrofluoric acid⁴.

Re: Predict which of the following compound will dissolve in the diluted HNO₃ but not in H₂O
I answered generally., if you check my first answer. MgF2 is soluble in HNO3 but also in higher concentration.
I already agreed above that MnS is soluble in nitric acid.
Now stop it please.
