Tin Standard Solution preparation

Tin Standard Solution preparation:



Tin Standard Solution (5 ppm Sn):


Dissolve tin  equivalent to 0.500 g of Sn in a  mixture of 5 mL of water and 25 mL of hydrochloric acid and dilute to 1000.0 mL  with water. Dilute the solution to 100 times its volume with a 2.5 per cent V/V  solution of hydrochloric acid immediately before use.
