Hi, Can anyone suggest a protocol for preparing 1 Litre ammonical solution (pH 7.8, NH4-N, 3000 mg/L) from NH4Cl and NaOH? I have worked out that I need 10.7g NH4CL and 0.45 g NaOH -is this correct? I am assuming that 1st step is to prepare 0.45 g NaoH in 0.5 L distilled water and then to that add 10.7 g NH4CL solution in 0.5 L of distilled water.Total volume is 1 L? Or is there another way
