pH isn't the only thing that plays into it.
The most dangerous acid in the world is hydrofluoric acid--they want you to call it HF because "hydrochloric" and "hydrofluoric" sound a lot alike. If you get this on enough of your skin, it will absorb into your skin, pull all the calcium out of your blood and kill you. 49 percent HF has a pH of 3.4--making it technically less acidic than 5-percent acetic acid at pH 2.4 or lemon juice at pH 2.2. Those acids are so dangerous you can drink a whole bottle of them and not be harmed.
You have to look also at what acid you're dealing with and what it dissociates into. Hydrochloric acid dissociates into hydrogen, which is pretty safe, and chlorine, which is really dangerous.
because it is corrosive
It isn't. the pH of Bleach is ~12.6, making it a highly basic substance. (Basic is the opposite end of the spectrum from acidic, but extremes of either are both dangerous.)
A normal or neutral pH level is 7. Caustic soda is highly basic with a pH of between 13.5 and 15. Caustic soda is a dangerous base and should be handled carefully.
pH 0 < acidic < pH 7 neutral = pH 7 pH 7 < basic < pH 14
The pH of basic solutions are greater than 7.
Just the other way round: 6.8 is an ACIDIC, pH, 7.8 is a BASIC pH.

It is either too acidic or too basic
A normal or neutral pH level is 7. Caustic soda is highly basic with a pH of between 13.5 and 15. Caustic soda is a dangerous base and should be handled carefully.
The higher the pH, the more basic, so a pH of 8 is more basic than a pH of 6.
pH 0 < acidic < pH 7 neutral = pH 7 pH 7 < basic < pH 14
This is a basic pH.
Acidic: pH < 7 Basic : pH > 7
The pH of basic solutions are greater than 7.
A basic pH is higher than an acidic or neutral pH.
Just the other way round: 6.8 is an ACIDIC, pH, 7.8 is a BASIC pH.
The strength of a basic solution is represented by the pH of the solution. The greater the pH, the more basic the solution. Solutions with a pH greater than seven are considered to be basic.
