可乐、雪碧等碳酸饮料深受大家欢迎,尤其是在炎热的夏季,是人们消暑解热必不可少的饮品。但是你知道吗?这些碳酸饮料中还蕴含了许多化学知识。下面就让我们以雪碧汽水为例一起探究一下吧。一、汽水中有什么气体?用注射器吸取适量石灰水,然后振荡雪碧汽水瓶,用注射器针头刺破瓶体,观察到气体冲入注射器,石灰水变浑浊了。这说明逸出的气体是二氧化碳,汽水中溶解了大量的二氧化碳。二、为什么汽水中能溶解较多的二氧化碳气体?用注射器吸入一定体积的水,再吸入大约两倍体积的二氧化碳,振荡。可以观察到,注射器活塞会 Coke, Sprite and other carbonated drinks by everyone, especially in the hot summer, is essential for people to relieve heat summer heat drinks. But do you know that these carbonated drinks also contain a lot of chemical knowledge. Let’s take Sprite water as an example to explore together below. First, the gas in the gas? With the syringe to absorb the amount of lime water, and then vibrating Sprite bottle, with a syringe needle piercing the bottle, the gas into the syringe was observed, the lime water becomes turbid. This shows that the escaping gas is carbon dioxide, which dissolves a lot of carbon dioxide. Second, why carbon dioxide gas can dissolve more? With a syringe inhaled a certain volume of water, and then inhaled about twice the volume of carbon dioxide, oscillation. It can be observed that the syringe piston will
