Which is a difference between strong and weak acids?

i think strong acids have a strong PH and weaker acids have less PH?!

Strong acids completely dissociate into their ions in water, while weak acids only partially dissociate.

Strong acids, like lye, can harm u because they eat through your skin, and weak acids, like lemons, can hardly do you anything accept that they burn when they come in contact with skin that's cracked or open ...

Hope this answers your question!
