NH4Cl係唔係白色架??

其他NH4 compound應該大多數都係白色ge~
除非本身佢ge anion有顏色...
咁佢ge compound先會唔係白色
所有NH4 compound都會dissolve in water ga wo
其實所有sodium,potassium同ammonium ge compound都會溶響水
唔係話dissolve in water 就會冇顏色ga wo@@
copper(II) sulphate係藍色ge~
佢dissolve in water後都會係藍色ga
正如當你加iron(II) chloride落dilute sodium hydroxide
佢出黎ge precipitate會係綠色一樣
iron(II) chloride solution本身會係淺綠色
iron(II) ion係pale green ge~
但係當form 左solid compound就會深色左...
正如你張d水彩加落水倒隻水彩d顏色會淺左
因為你多左空間俾d有顏色ge particles走...咁就淺色左
反之你少左空間俾佢走...
佢未睇落深色d咁解咋ma

Ammonium Chloride SOLID and GAS are white in color, but its solution is colorless,
Ammonium ion is colorless, so most of ammonium compound is colorless when dissolved in water but white when in solid form, except the anion has characteristic color.
