Feldspar, a major constituent of most igneous rocks, reacts with carbonic acid to produce residual clay minerals plus dissolved ions of metals (potassium, sodium or calcium, depending on the type of feldspar). Here, for example, is the reaction by which potassium feldspar is converted to kaolinite, a clay mineral: 4KAlSi3O8 + 4H2CO3 + 2H2O → Al4Si4O10(OH)8 + 4K+ + 4HCO3- + 8SiO2 feldspar + carbonic acid + water → kaolinite + dissolved potassium and bicarbonate ions + dissolved silica Similar reactions affect sodium feldspar and calcium feldspar.

What does HCO3 stand for?
Carbonic acid
How is carbonic acid formed?
Carbonic acid (H2CO3) is formed when carbon dioxide is dissolved in water under pressure. But carbonic acid is unstable, and under atmospheric pressure, decomposes to water and carbon dioxide. H2O + CO2 ---> H2CO3
What forms when water mixes with carbon dioxide gas in the air or soil?
A weak acid called Carbonic Acid form. Fun Fact: This is the same weak acid that is found in many soft drinks.
Is acid rain is made from small amounts of acetic and carbonic acids?
Acid rain contain carbonic acid, sulfuric acid, nitric acid.Acid rains are very dangerous for metallic structures and plants.
Does carbonic acid affect your pulse rate?
yes
What happens when carbon dioxide in exhaled air is mixed with water?
It dissolves and forms carbonic acid, by: CO2,g + H2Ol --> H2CO3,aq , a very weak diprotic acid.
What happens when sulphuric acid is mixed with sodium carbonate?
Sodium Sulphate, Carbon Dioxide and Water OR Carbonic Acid
What is carbonic acid abd how does it effect chemical weathering process?
Carbonic acid is an acid formed by diluting co2 in water. It weathers calcite minerals by reaction with them (Lime stone)
What color does BTB turn when mixed with a acid or a base?
It forms carbonic acid and turns yellow
What happens when you mix carbonic acid and alum?
Nothing
When rain and CO2 combines what happens?
Carbonic acid is formed.
Why a carbon dioxide is called an acid anhydride?
Carbon dioxide is so called because when it mixed with water it give carbonic acid that is why it known as acid anhydride.
What effect does carbon dioxide have on water when mixed?
It partially forms dihydrogen carbonic acid, which is a very weak acid.
What product is formed when the carbon dioxide is dissolved in water?
When mixed with water, carbon dioxide forms carbonic acid. It should be noted it only partially dissolves. If temperatures dip below -78c, it will become solidified again.
What happens when carbonic acid reacts with calcite?
calcium bicarbonate is formed
What is dilute carbonic acid?
Dilute carbonic acid is a carbonic acid solution that is in low concentration.
Carbonic acid is a mixture of what?
Carbonic Acid is water reacted with carbon dioxide.
