解析 Yes, carbon dioxide (CO2) is indeed an acidic oxide. 二氧化碳 (CO2) 是一种酸性氧化物,因为它能与水反应生成碳酸 (H2CO3),一种弱酸。这个反应可以表示为:CO2 + H2O → H2CO3。这种性质使二氧化碳在许多化学反应中扮演重要角色,例如酸雨的形成和人体呼吸作用中调节血液 pH 值。
Joseph Black, a Scottish chemist and physician, first identified carbon dioxide in the 1750s. At room temperatures (20-25 oC), carbon dioxide is an odourless, colourless gas, which is faintly acidic and non-flammable. Carbon dioxide is a molecule with the molecular formula CO2. The linear ...

They absorb more than 25% of all the carbon dioxide that people emit into the atmosphere. As a result, the ocean's water is becoming more acidic. This change af-fects the food chain and all 13 organisms.14 carbon dioxide is not poisonous in normal amounts it can kill you if there ...

Extra carbon in the ocean will make the water more acidic (酸性的), putting sea life in danger. The WMO report said the rise inCO2 levels is happening faster than fossil fuel use, so the planet's natural ability to absorb carbon may be slowing down....
