Can water quality be judged by water electrolysis experiments?

In fact, electrolyzed water cannot prove water quality at all.

Anyone who has studied chemistry knows that compared to pure water and salt water, salt water has better conductivity.

However, good conductivity does not mean that the water quality is good, and poor conductivity does not mean that the water is bad.

Because if there are acids, alkalis and salts in the water, they can increase the electrolysis of the solution.

In addition, the materials used for the positive and negative electrodes also have an impact. Use copper rods, iron rods, zinc rods or carbon strips. The conductivities of these materials are also different.

The electrodes will ionize the copper or iron rods inserted into the liquid and dissolve them in the solution. Because the copper and iron ions are colored, you will see that the liquid slowly becomes cloudy. meansIf the previous water was dirty, this can only prove that something dissolved in the liquid.

I remember once watching a video of a businessman from Wechat, talking about the quality of the products they made, and then they tested the conductivity of tap water, mineral water and their products, and the result was: Tap water and mineral water only make the bulb a little brighter, but their product directly makes the bulb light up, as if it were installed directly on the socket, it is very bright. This is why this micro-business brags about its products.

But anyone who has learned chemistry knows that it's just a matter of conductivity. It has nothing to do with water quality.

If you take a cup of pure water and use two carbon strips, it is estimated that even the light bulb will not light up. However, if you use salt water and carbon strips, because itthere are ions. Water, this can increase the conductivity and make the bulb brighter.

As before, some people said that water could turn into oil and that iron could turn into gold. These actually use certain principles of chemistry or physics to deceive strangers.

However, it is true that many people, especially the older generation, and those who do not like to read, cannot clearly see the essence of certain things, which allows some scammers easily take advantage of them. Therefore, read more books, read more newspapers and increase your knowledge.

Is it true that the post-85 generation in Chengdu has created a plug that is not afraid of water?

Aren't the light bulbs in your house energy efficient? Is he the old-fashioned rotund guy? This type of bulb generates heat after prolonged use. The higher the temperature of theThe bulb is long and the water temperature is relatively low. a high temperature bulb meets water, it will become hot and cold. When a low temperature bulb comes into contact with water, it has a cooling effect and the water vapor produced is the smoke you see.

There is a kind of light bulb with a sealed lamp holder. It looks like there is a layer of special coating on the outside. When the lamp holder is exposed to water, it will light up when held. a mobile phone. What is the principle ?

It's true.

FS (Fence out Something) isolation connection technology independently developed by Zhou Gang, a post-85 generation in Chengdu, solves the three major safety problems of traditional exposed connection technology: " leakage, short circuit and arc", achieving both isolation and energization.

From the outside, the Algon insulated electrical outletre is no different from an ordinary three-hole household socket. The shell material is flame retardant PC plastic, gray or gold. There is a circle outside the three holes and a thin strip-shaped indicator. The light above turns on when the device is powered on. As for the plug with bulb used for demonstration, the appearance of the metal triangular plug is the same as that of an ordinary plug.

Life buoys and vests used on seagoing vessels are equipped with light bulbs that automatically flash when exposed to water to send flash signals for energy help. This bulb has an automatic switch integrated into the battery pack. Normally the switch is off and the bulb does not light up. During use, if the life jacket or life buoy falls into the water, the bulb battery device will be immersed in the water. Water conductivityis used to automatically turn on the power switch of the bulb - and the bulb lights up.
