What is the pH of a solution prepared by dissolving 7.0 g of tris (FM 121.14) plus 12.0 g of tris hydrochloride (FM 157.60) in 250 mL water
Answers: 1
![pH=pKa+log(\frac{[TRIS]}{[TRIS-HCl]} )](/tpl/images/0840/1861/f36e1.png)
![[TRIS]=\frac{7.0g/(121.14g/mol)}{0.250L}=0.13M](/tpl/images/0840/1861/06315.png)
![[TRIS-HCl]=\frac{12.0g/(157.60g/mol)}{0.250L}=0.305M](/tpl/images/0840/1861/7f3d9.png)
