Which is harshest to the skin: An acid or a base?

I'd say acid. A base will corrode the skin, but an acid will burn. Trust me, it hurts.

well this question was asked two days before.\nsearch for this question u'll get all the knowledge\nstrongest oxo-acid-- HClO4\nstrongest protonic acid--H2SO4\nstrongest lewis acid----SBF5\n btw HF is not consider very strong bcoz F is very small atom and it does not loose H+ very easily.\n\nEDIT: Question(very odd name) there has been acids with negative pH and 0 pH( 0pH is more stronger than 1)

So you want to put a chemical on your skin that is going to burn the top layers of your skin off?\n\nI think not\n\nIf you make a mistake it will scar you for life.

Depends where you look for, in the stomach is about 2 while in the mouth is slightly basic (about 6) due to the pH buffering power of the saliva. In general the overall pH is about 5.5 (same as many soaps for delicate skin). This is not a comprehensive answer because for example the skin pH is influenced by many external factors (bacteria, cleanliness, pH of sweat etc.)

water, rubbing alcohol or if nothing else acid :P(dont really do acid)

Sulfuric Acid- just learned that today... check the link for more info...\nit is a VERY strong acid!

Concentrated Nitric Acid and copper.  Be careful.  Nasty stuff... really!

They will use the acid to remove the tattoo but acid is somewhat concentrated. if we use it remove the tattoo but it creates wound instead of removing and we will get scar on the place which we have decided to remove it

depends on the skin condition, need more info

Acids.\n\n0-7 = Acid\n7 = Neutral\n7+ = Base

Acidic \n\nbelow 6 acidic above 7 basic

NaOH is a strong base, if you spill it on urself you will burn.  The amount you will burn depends strongly on the concentration of the solution. For example, if you have 100% NaOH spilled on you, you will burn very bad, VERY bad.  Strong bases are just as bad as strong acids because they are so reactive with your skin, so be careful.

HNO2...all others are strong acids.

an acid is a proton donor while a base is a proton acceptor or an electron donor\n Hope i'm right
