It can, but not for long.
NO! Mayonnaise contains raw egg whites, which will spoil if left as long as overnight. You can leave it out for a max of an hour, but overnight is definitely ruined. If you ate mayonnaise after it is left out and feel queasy, you should consult a doctor. Hope you didn't... :-)
Potato salad should not be left unrefrigerated for more than two hours. Less time is better. In fact, if the ambient temperature is around 90°F, cut that time to less than 1 hour.
Probably the creamy sauce or mayonnaise used to dress potato salad is the culprit if people feel unwell or suffer from digestive problems after eating the salad. It is very important that any dish such as pasta salad, rice salad and potato salad which is served cold in a creamy sauce should be refrigerated until the moment it's served, and then served quickly and not left out in a warm environment. This is asking for food poisoning. Pregnant women are particularly at risk with this type of food, as with pates and soft cheeses. As a rule of thumb, keep cold foods cold and hot foods hot, refrigerate both as soon as serving is finished and discard if not used within a day.

Potato salad will never be as good as when it was first made. Use it within a day or two. Depending on what you put in your potato salad will depend on how long your salad will last. If you put eggs in your salad then you have 3 days to use it up in. If you omit the eggs then you have about 5 days as long as the salad doesn't sit out and get warm since it has mayonnaise in it.
Is salad dressing a heterogeneous or homogeneous mixture
No, it cannot. As soon as the mayonnaise reaches room temperature, it should not be eaten.
Mayonnaise is safe to eat if cooked or baked on foods. Mayonnaise can be used a a cake to give it a rich flavor.
It wouldn't be safe to eat salad that's been left out overnight.
For sure! You can get food poisoning from eating mayonnaise that has been left out of the fridge too long, and it spoils quicker with increased temperature.
I would say about 4- 5 days after being made. Most likely has been out in the sun at a party or has got warm by being left out.
