All alkali (Group 1A) compounds are soluble. Sodium & Potassium
All halogen compounds are soluble except those containing Ag+, Hg2+, or Pb+2)
All nitrates (NO3-), chlorates (ClO3-) and perchlorates (ClO4-) are soluble. Most sulfates (SO42-) are soluble. Calcium sulfate is slightly soluble.
All carbonates (CO3-2), phosphates (PO4+3), sulfides(S-2) are insoluble.

Do the abundance of the elements change? In other words, do elements change into other elements?
Are elements formed in the caldron of a volcano? Are elements changed to other elements in the intense heat of a volcano (about 1,000oC for lava and 2,000oC for inside volcano)?
Elements may separate from other elements or combine with certain elements. There is not enough heat in a volcano to change an element into another element. Here is silicon and oxygen with trace amount of metals (darkening) to form a mineral called…

The core with a mass of ½ million Earths shrinks from 1000 km (600 mi.) to about 50 km (31 mi.) in 1 second. Implosion velocity reaches 170 million mph...about 1/4 c or 50,000 miles per second.
Helium Carbon Neon Oxygen Silicon The outward moving matter is moving so fast that it compresses and heats whatever it collides with to temperatures of 1010 to 1011 K... much hotter than anything we have encountered in our studies of stars so far.
