4.0g of potassium hydrogen tartrate was added to 300mL distilled water. The temperature of the solution is 23.1C. The liquid was filtered and 50mL of the filtered solution was transferred to 250mL beaker, two drops of phenolpthalein was added to the 250mL beaker. The concentration of NaOH is 1.0 M that is filled in the 2mL graduate pipette, single drops of NaOH was added to the 250mL beaker until the solution turns pink and the potassium hydrogen tartrate reach the endpoint. The datd of four trials was collected. Please answer the following questions 4) calculate ksp for potassium hydrogen tartrate for each trial and average ksp for thr experiment 5) calculate the percent error in you value of ksp using reference that is found as the theoretical value. 6) why was the temperature of the saturated solution recorded?
