Understanding Acids, Alkalis, Indicators, and the pH Scale

Solutions can be acidic, alkaline, or neutral depending on whether an acid or alkali is dissolved in water. Indicators like litmus and universal indicator help determine acidity or alkalinity. The pH scale measures this, with 7 being neutral. Neutralization reactions occur when an acid and a base re

Carbonates Replacing Plagioclase Glass in Martian Meteorite ALH84001

The carbonates replacing plagioclase glass in the Martian meteorite ALH84001 have raised questions about their origin - whether they are biologically formed or through other geological processes. Discovered in Antarctica in 1984, this meteorite has been dated to over 4 billion years and initially mi
