NaCl 시약으로 1000 ppm Cl^- 용액 만들기

NaCl 시약으로 1000 ppm Cl^- 용액 만들기

 

 

Prepare a 1000 ppm stock solution of chloride ions from solid sodium chloride.

 

---------------------------------------------------

 

1000 ppm = 1000 mg/L

( 설명 https://ywpop.tistory.com/5345 )

 

 

1000 mg = 1 g Cl^-

 

 

1 g Cl × (58.44 g NaCl / 35.45 g Cl)

= 1 × (58.44 / 35.45)

= 1.6485 g NaCl

 

 

If you dissolve 1.6485 g of sodium chloride in 1 L of water,

you'll get a 1000 ppm Cl^- solution.

 

 

답: 1.6485 g
