Even though I already know that purified water is acidic, but the water test still shocks me, the yellow result is from the purified bottle water, and the green one is from the filtered water from my home's machine (the machine keeps good minerals and filtered out heavy metal), It tells us that we need to reduce purified water daily, since it doesn't have any minerals, and we have 70% water in our bodies, the more pruified water the more acidic body fluid will be, and it won't make you a healthy body.
水的实验：有些瓶装水真的是酸的

Don't worry! From google: Pure distilled water would have tested neutral, but pure distilled water is not easily obtained because carbon dioxide in the air around us mixes, or dissolves, in the water, making it somewhat acidic. The pH of distilled water is between 5.6 and 7.
