Alkaline based superpower???

I'm wondering, we know there are acid based superpowers, but what are the uses of a super power that produces basic instead of acid? What are its utility other than simply for corroding stuff? Anyone got some insights on this? Suggestions of creative use?

As Rule of Thumb: 1. Anything that can be harmed by acid, is usually impervious to alkaline. But the reverse is also true; anything cannot be harmed by acid, will seriously messed up by alkaline. That's why tanning industries used alkaline, folks. 2. Also, alkaline is usually pricier than acidic stuff. Most common naturally formed alkaline in RL is limestone, which, compared with many acidic stuff, usually produced by living things, aren't very abundant. 3. Alkaline are far more useful as binding agent for building and agricultural terraforming (there's much more acidic soil than alkalic soil). 4. Alkaline metal, which is main component of many salt and some naturally-forming alkaline, are very reactive. Seriously, this stuff can burn water. No, I'm not making this up.

They don't burn water. They react with water to form a metal hydroxide and hyrdogen gas (in the for of 2X + 2H2O -> 2XOH + H2 where X is the alkali metal in question, Na for Sodium, K for Potassium etc). The reaction is exothermic so the hydrogen gas ignites, but its not the water itself.

Yep. The water burns the metal as the water is the oxidising agent.

Well, it seems that the water is on fire, if nothing else (pouting).

Also, I kinda forgot, alkaloid. Basically, natural-produced base compound, organic, contain no metal, and slightly alkaline.

If it came from plant, it makes you groovy and/ or healthy, 90% chance that it's an alkaloid or it's derivative.

Let's not forget that "acids" in fiction are usually bright-colored liquids or goos that eat through anything, unless the plot requires something to be impervious to it. They don't have much to do with actual acids. Even if you're going for acid-based powers that are true to the chemistry of acids, alkaline-based powers will probably be met with confusion and comments of "so this just an other kind of acid, why give it a different name?"

R Bomber, flesh is seriously messed up with either acid or alkali. They both are corrosive to flesh.

Nitric acid is corrosive, citric acid, relatively, is not. So does malic acid, most of amino acid, carbonate acid. Please don't mix out strong and weak reactant.

Funnily enough one of my OCs for a WIP kind of has this... although the power is extremely squicky.

Long story short she can control production and concentration of fluids/mucus/enzymes within her GI tract and thus can produce lots of extremely strong gastric acid or extremely caustic alkaline gastric mucus, both of which have very fast-digesting enzymes that eat through organic matter in seconds.

She of course puts that stuff into a water gun (the plastic make doesn't get dissolved by acid or alkali) as her ranged weapons. It helps that her enemies tend to be organic, mutated zombies.
