Is Li+ soluble in water?
Salts containing Group I elements (Li+, Na+, K+, Cs+, Rb+) are soluble .
Does NH4+ form soluble compounds?
The Na+, K+, and ammonium (NH4 +) ions form soluble salts. Thus, NaCl, KNO3, (NH4)2SO4, Na2S, and (NH4)2CO3 are soluble.
Is NH4CH3COO soluble or insoluble?
Ammonium acetate (acetate of ammonia) is a colorless crystalline mass consisting of extremely hygroscopic small needle-shaped crystals. At a temperature above 144°C, the reagent undergoes decomposition forming acetamide: NH4CH3COO = CH3CONH2 + H2Ob. It is very soluble in water (58.6% at 4°С), soluble in ethyl alcohol.
Is K+ soluble?
Solubility of potassium and potassium compounds Potassium is non-water soluble, but it does react with water as was explained earlier. Potassium compounds may be water soluble.
Is F soluble in water?
Is CU soluble in water?
Copper forms compounds in the oxidation states +1 and +2 in its normal chemistry, although under special circumstances some compounds of trivalent copper can be prepared. The pure compound is insoluble in water but soluble in hydrochloric acid or ammonia.
Is BA OH 2 soluble or insoluble in water?
Barium Hydroxide is a strong Arrhenius base, so it will almost completely ionize. It is soluble, but barium carbonate is not.
How do you know if a salt is soluble or insoluble?
If there two rules appear to contradict each other, the preceding rule takes precedence.
- Salts containing Group I elements (Li+, Na+, K+, Cs+, Rb+) are soluble .
- Salts containing nitrate ion (NO3-) are generally soluble.
- Salts containing Cl -, Br -, or I – are generally soluble.
- Most silver salts are insoluble.
Why is potassium more soluble than sodium?
Distance: Since potassium is larger, the distance between the somewhat negative oxygen in water and the positive charge of the nucleus of potassium is larger than that of sodium, and since the EM force is so dependent on distance, this force would be less and thus the tendency of water to be ‘trapped’ about it would be …
