1. Determine the pH of the buffer solution that is prepared bymixing 259 mL of 0.0983 M BIS−TRIS propane−H (C11H27N2O6+ ) to 855mL of 0.0729 M BIS-TRIS_propane (C11H26N2O6) ). Assume the 5%approximation is valid. Report your answer to 2 decimal places. ThepKa of BIS−TRIS propane−H is 9.10. Submit Answer Tries 0/3 2.Determine the pH of the BIS−TRIS propane−H/BIS−TRIS propane buffersolution after the addition of 25.2 mL of 0.643 M solution ofrubidium hydroxide to the existing buffer solution. Assume the 5%approximation is valid.
