Obsidian, being a volcanic glass composed primarily of silica, does not react with vinegar (acetic acid) in the same way that limestone or other carbonate rocks do. Since obsidian lacks calcium carbonate, there is no fizzing or bubbling reaction when vinegar is applied. Instead, the surface of the obsidian may become slightly cleaner due to the acidic nature of vinegar, but there is no significant chemical reaction.
What else can I help you with?
What happens when you put obsidian in vinegar?
When you put obsidian in vinegar, there is typically no significant reaction because obsidian is primarily composed of silica (silicon dioxide), which is chemically inert to acetic acid found in vinegar. However, any surface contaminants or minerals present on the obsidian may react slightly, but the obsidian itself will remain largely unchanged. Overall, you won't see any notable effects from the interaction.
Name 4 kinds of igneous rocks?
Examples of igneous rocks are pumice, obsidian, basalt, and rhyolite.
What does obsidian mean in rocks and minerals?
Obsidian is black glass formed by volcanoes.
Why do obsidian rocks look dark?
because an obsidian rock has low silica
What type of rocks are pumice obsidian and granite?
Igneous rocks
What are rocks that have a glassy texture called?
Obsidian
Why does vinegar cause sedimentary rocks to fizzle?
Vinegar, which is acidic, reacts with the calcite or limestone present in sedimentary rocks, resulting in the release of carbon dioxide gas. The fizzing or bubbling you observe is the visible evidence of this reaction. This reaction between the acid and the calcium carbonate in the rock is similar to the reaction that occurs when acid is added to baking soda.
What is a glassy rock?
Glassy rocks are rocks that have cooled and solidified quickly, without forming crystals. This rapid cooling prevents mineral crystals from growing, resulting in a smooth and glass-like texture. Obsidian and pumice are examples of glassy rocks.
What are very smooth rocks called?
Very smooth rocks are called "polished rocks" or "river rocks" due to the smooth texture achieved from erosion in water bodies like rivers and oceans.
How long have obsidian rocks been around?
A while.
Is the obsidian trilogy good?
oh it rocks! You have to read it
What is it called when igneous rocks cool quickly?
obsidian
