B. It acts to hold the vinegar and oil together in a colloid.

Explanation:

Egg yolk contains lecithoprotein and yolk is an emulsion. An emulsion is a temporary stable mixture of immiscible fluids. It functions as an effective and efficient emulsifying agent. It emulsifies by reducing surface tension and reduces the force which is needed to make the droplets that comprise an emulsion. Thus, egg yolk holds or stabilizes oil and vinegar together.

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!
