Question

Please show all work! Thank you :)

Prepare 100 mL of 0.1 M Tris HCL and 0.1 M Tris base.

Molecular weight Tris HCL = 157.56g

Molecular weight Tris Base = 121.14g

Part A: Mixing 0.1 M Tris HCL with 0.1 M Tris base to acheive a pH of 7.8 what is the theoretical volume of 1.0 N HCL needed

Part B (1): Titrating 0.1 M Tris base with 1.0 N HCL what is the theoretical volume of 0.1 M Tris required?

Part B (2): Agreement between calculated and measure volume of HCL needed: Calculate accuracy. Explain error greater than (+/-) 5%

Explanation / Answer

Part B:

(1) By the volumetric equation:

M1xV1(Tris base)=M2xV2(HCl)

0.1MxV1=1.0Mx 100mL

V1 of Tris Base= 1000mL
