Answer for USA, Canada and countries running a 60 Hz supply service.
White goes to neutral. White is an incorrect color for ground.
Upon further investigation you might find, however, that the white wire is connected to the casing of the appliance. If this is true and if this is the only function of the white wire then it is truly a ground wire. It should be wired as such to the outlet and it should be marked on both ends with green tape or paint or some other method of marking, or it should be replaced with a green or bare conductor.
If it serves the purpose of ground and neutral you may want to consider replacing the cable with a 4 conductor cable and isolate the neutral from the ground.

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.

The red and black wires are your hot wires, which should connect to the two brass terminals on the outlet. The white wire is your neutral wire and should connect to the silver terminal on the outlet. The green or bare wire is your ground wire and should connect to the green terminal on the outlet.

What is a U-ground outlet?
A U-ground outlet, also known as a NEMA 5-15R outlet, is a type of electrical outlet commonly found in homes and commercial buildings. It has a horizontal slot for the neutral prong and a vertical slot for the hot prong, with a semicircular hole underneath for the ground prong. This design helps ensure that the outlet is properly grounded for safety.
How do you put on a four prong outlet on a roper electric dryer?

Can you change outlet to fit old 3 prong outlet?
You can use a grounding adapter to convert a 3-prong outlet to fit a 2-prong outlet, but this may not provide grounding protection. It is recommended to hire a professional electrician to upgrade the outlet to a proper 3-prong outlet for safety.
Which wire in a 240V cable with black white and bare copper wires connects to which prong in a 3-prong 30-amp 120-240V dryer outlet?

Where do you ground the extra wire when plugging a 4 prong wire into a three prong outlet for a dryer at?
If you are connecting a 4-prong dryer cord to a 3-prong outlet, the extra ground wire (green or bare copper wire) should be left unconnected. Do not try to ground it by connecting it to the neutral terminal or anywhere else. This is to prevent creating a ground loop and potentially causing a safety hazard.

Yes, provided that you have a ground wire in the box and that the ground wire is properly connected in the electric panel.
Can you replace a 2 prong outlet with a 3 prong outlet if there is no ground line or is the ground required?
Yes, you can replace a 2 prong outlet with a 3 prong outlet, but you should use a GFCI outlet instead, which provides some level of shock protection even without a ground wire. However, it's best to have a qualified electrician install a ground wire for proper safety and functionality.
How do you test for groung on a two prong outlet?
Buy a tester. They are very cheap and will tell you at a glance if the outlets are wired correctly. The only other way is to remove the outlet and look see. But if it is a 2 prong outlet with no ground hole then it does not have a ground.

It's important to match the plug with the corresponding outlet for safety and proper functionality.
