Exposure to iced bottled water tested for strong acidity up to pH 5.0

Ms. Huang had to use bottled water for laundry.



Ms. Huang added PH test agent to the pure water of the ice dew, and the water immediately became brown. The PH value was compared to 5.0 or so.



The left is pure brown iced water, and the right is tap water. The color of sea blue is green and its pH is about 7.5.

16 yuan a bucket of bottled water to wash clothes, this is not a luxury waste, but too helpless! Recently, Ms. Huang, who lives in Fangcun Village, posted on the Internet and said that she had self-tested some brands of bottled water and found that the PH value was only about 5.0. The acidity was so strong that the whole family was worried and never dared to drink. It was all used to wash clothes. .

Public self-test: ice exposed bottled water PH value 5.0

In August of last year, Ms. Huang spent $160 in a shopping mall near her hometown and ordered 10 barrels of iced bottled pure water. Because the brand belongs to The Coca-Cola Company, Ms. Huang could safely drink it. In November last year, they called the first bucket of water. On April 26 this year, they called another bucket of water. "I often feel uncomfortable during the drinking of this water and I suspect that there is a problem with the water. Then I took the PH test agent and the result surprised us." Ms. Huang said that after testing, the second bucket of water had only a pH value. About 5.0, while the test of the home's tap water PH value is about 7.5, while the Other home a certain brand of mountain spring PH value of about 7.0.

Ms. Huang said that the PH value of iced barreled purified water is much lower than that of tap water, showing more obvious acidity. In this way, “acid water” they no longer dare to drink.

In order not to waste water, Ms. Huang decided to use all the remaining iced bottled water to wash clothes. “Even if you don’t dare to wash the dishes.”

Yesterday afternoon, the reporter went to Ms. Huang’s house. The family just put a barrel of iced bottled water that had just been delivered over the day. The reporter opened the bucket of water and started testing the PH value.

In a small bowl full of iced bottled water, the reporter dripped in the pH test solution. The water in the bowl immediately became brown, and the pH value was about 5.0. The reporter then picked up the water from Ms. Huang’s home and dripped into the pH test solution. The transparent water immediately turned into a navy blue with a pH of around 7.5. Using the same method, the PH value of a certain brand of spring water in the home was measured to be about 7.0. After adding the test solution, the water became grass green.

Three kinds of different drinking water, after adding the PH test solution, showed three distinct colors, and the contrast was quite strong.

Agent: If the PH value is indeed too low to replace the reporter then call the ice bottled water Guangzhou agent Baichuan water industry, for the reporter measured the value of the ice dew bottled purified water PH value of about 5.0, customer service staff said In general, the pH of iced barreled purified water is below 7 and belongs to weakly acidic water.

"Although there is no specific standard for this PH value, it should not be under such a low value of 5.0 under normal circumstances." Customer service said that if the customer does have doubts about the brand of bottled water, they can send someone to the door to test it. The figures are indeed too low and customers will be considered to replace other brands of bottled water.

Experts: It may be that the barrels have not been washed when disinfected. It is not recommended to drink weak acids for a long time. Jiang Zhuoqin, professor of Department of Nutrition of the School of Public Health at the College of Water Sciences of Zhongshan University, told reporters that the pH values ​​of distilled water, mineral water, and purified water are generally more than 6 points, and the PH value is 5.0. The water belongs to weakly acidic water.

For Ms. Huang, the value of the ice dew purified water PH value of about 5.0, Jiang Zhuoqin said that because it is a family test, this figure may have errors. But at the same time, he also stated that it is also possible that there is a problem with the disinfection of barrels containing water in the production process. “There may be barrels that are disinfected with acid disinfectants but they are not cleaned.” Another possibility is that the brand is barreled. Water microorganisms exceed the standard, microbial metabolism produces acidic substances, resulting in a lower PH value.

Jiang Zhuoqin also added that for weakly acidic water, the public need not worry too much. "Usually we drink Coke and Sprite PH values ​​are acidic." Jiang Zhuoqin said that the long-term consumption of acidic water will lead to calcium loss and other issues, for the presentation of weak acidic bottled water, he does not recommend the public long-term drinking. Experts said that for ordinary people, the PH value is more suitable for drinking from 6.0 to 7.5, and neutral water with a pH of about 7.0 is the best. When choosing bottled water, he suggested that it is best to choose a brand with clean water and no pollution around.
