Does acidic lava have a low melting point
Did you know?
WebMelting points. The amino acids are crystalline solids with surprisingly high melting points. It is difficult to pin the melting points down exactly because the amino acids tend to decompose before they melt. Decomposition and melting tend to be in the 200 - 300°C range. For the size of the molecules, this is very high. WebNov 5, 2024 · Crater lakes atop volcanoes are typically the most acid, with pH values as low as 0.1 (very strong acid). ... Explanation: “Acid lava is highly vicious in nature, with high melting point, it is light in colour, it is high in silica content, it is slow moving and it comes from cone volcanoes whereas basic lava is non-vicious in nature, it is ...

WebMelting point principle: as the molecular weight increases, the melting point increases. This observed in the series lauric (C12), palmitic (C16), stearic (C18). Room temperature is 25 o C, Lauric acid which melts at 44 o is still a solid, while arachidonic acid has long since melted at -50 o , so it is a liquid at room temperature. holista chardon marieWebJan 5, 2024 · So you should say that lactic acid has higher melting and boiling points becuase it contains a (or: one) hydroxy group while pyruvic acid has a carbonyl group in the same position.
