This is databook entry of her jutsu :
Also according to Narutopedia anime make mistake when they first time show this jutsu as pure Lava :
And later they did it properly
So is her jutsu melting because of extremely hot temperature or because of strong acid ???
Lava Release: Melting Apparition Technique (溶遁・溶怪の術, Yōton: Yōkai no Jutsu)
Heading: Manipulating the strong acid of a large volcanic mud flow to corrode ones flesh.
Classification: Ninjutsu/Kekkei Genkai
Rank: No Rank
Class: Offensive
Range: Shot to Mid-Range
User(s): Terumī Mei
For the Fifth Mizukage it's possible to use the Lava Release Kekkai Genkai. Inside her body, Chakra is changed into strong acidic fluid, everything is melted by the dangerous technique. Out of the mouth gushes (blasts) out a quantity of viscous fluid, the shape and amount is at the liberty of the technique's users. When spit forth at short range it's speed drastically increases (I'm pretty sure?), a wall that obstructs ones path, to use in more than one direction is feasible.
↑ Distributes viscous liquid across a vast range/scope, creating an acid wall. Anything that touches it will crumble and loose it's shape.
