Answer:
In blood: Dispersed phase: blood cells; Dispersed medium: liquid plasma
In fruit jelly: Dispersed phase: fruit juice; Dispersed medium: pectin
Explanation:
The dispersed phase refers to the phase where colloidal particles are dispersed within another phase, known as the dispersion medium.
In blood, the tiny cells act as colloidal particles, forming the dispersed phase within the liquid medium identified as plasma.
Conversely, in fruit jelly, the fruit juice constitutes the dispersed phase while the solid pectin serves as the dispersed medium.
Answer:
The trial's estimated concentration of acetic acid in the vinegar would be higher than the true concentration.
Detailed explanation:
"The titrator" holds the base solution (NaOH) that will be used to titrate the vinegar solution (acetic acid).
If we assume that the syringe tip was not primed prior to recording the initial volume, a portion of the base solution that is released will be retained in the tip of the syringe, resulting in the actual volume of base added to the acetic acid being less than calculated based on the readings.
Consequently, in the calculations, a larger volume of the base is used than what was genuinely applied, which leads to an inflated number of moles of base compared to the actual amount utilized.
Thus, at the point of neutralization, where the equivalents of base equal the equivalents of acid, you will report a higher amount of acid equivalents, resulting in a calculated concentration that is greater than the true concentration. This ultimately means the concentration of acetic acid in the vinegar of that trial would be greater than the actual concentration.
