=VLOOKUP(Lookup_value, Table_array, Col_index_num, Range_lookup)) Lookup_value â The value you want to find in the lookup value column. Lookup_value â The table range containing columns for both the lookup and return values. Col_index_num â The index number for the column containing the return values.
--Ammonium salts have a hypothetical risk of ammonia toxicity. In addition to calcium levels, ammonia and phosphate levels should be monitored. --Potassium salts have a hypothetical risk of hyperkalemia which can cause cardiac arrhythmia.
The ammonium ion is a positively charged ion or cation and has the chemical formula, NH 4 +. Ammonium salts are commonly used in fertilizers. Examples of compounds containing the ammonium ion include, ammonium nitrate, NH 4 NO 3 and ammonium sulfate, (NH 4) 2 SO 4. All ammonium salts are soluble in water and dissociate or break down to produce aqueous ammonium ions. NH 4 NO 3 4 + (aq) + NO 3 - (aq) where aq = aqueous (surrounded by water) and s = solid. The ammonium ion is formed by the neutralization of the base ammonia, NH 3 with and acid. NH 3 + HNO 3 4 NO 3. NH 3 + H 2 SO 4 4) 2 SO 4. The ammonium ion has one co-ordinate covalent bond which involves the nitrogen atom donating two electrons in one of the N-H bonds.
