Write the formulas of the compound NH4+ formed by specified cations with the following anions:OH-, NO3-, CO3-2,HSO4-, PO4-3 . Use the given order of anions
There is no NH4OH although some people still use that as the product of NH3 + H2O. It has been shown not to exist.
NH4NO3
(NH4)2CO3
NH4HSO4
(NH4)3PO4
To write the formulas of the compound NH4+ formed by specified cations with the given anions, we simply combine the NH4+ cation with each of the anions. The formula for the compound NH4+ and each of the anions is as follows:
1. NH4OH: NH4+ combines with OH- to form NH4OH.
2. NH4NO3: NH4+ combines with NO3- to form NH4NO3.
3. NH4CO3: NH4+ combines with CO3^2- to form NH4CO3.
4. NH4HSO4: NH4+ combines with HSO4- to form NH4HSO4.
5. NH4PO4: NH4+ combines with PO4^3- to form NH4PO4.
These are the formulas for the compounds formed by combining NH4+ with each of the specified anions.
To write the formulas of the compound NH4+ formed with each specified anion, we need to determine the charges of the anions first.
1. OH- (hydroxide ion): The hydroxide ion has a charge of -1.
Since the ammonium ion, NH4+, has a charge of +1, we can balance the charges by using one ammonium ion for one hydroxide ion. Therefore, the formula is NH4OH.
2. NO3- (nitrate ion): The nitrate ion has a charge of -1.
Again, using one ammonium ion, NH4+, will balance the charge of one nitrate ion. The formula is NH4NO3.
3. CO3-2 (carbonate ion): The carbonate ion has a charge of -2.
In this case, we need two ammonium ions, NH4+, to balance the charge of one carbonate ion. The formula is (NH4)2CO3.
4. HSO4- (hydrogen sulfate ion): The hydrogen sulfate ion has a charge of -1.
The ammonium ion, NH4+, needs to be combined with only one hydrogen sulfate ion. The formula is NH4HSO4.
5. PO4-3 (phosphate ion): The phosphate ion has a charge of -3.
To balance the charge of one phosphate ion, we need three ammonium ions, NH4+. The formula is (NH4)3PO4.
Remember, when writing formulas, we represent subscripts using parentheses when needed to indicate the number of ions present in the compound.
