Water (pure) has a high surface tension;
which means that water tries to stick to itself ... and does a pretty good job of it.
"Wetting agents" act by lowering the surface tension of water.
countries with poor water example : Africa
Not wetting the salt bridge with a KNO3 solution can lead to poor ionic conductivity between the two half-cells in an electrochemical cell. This can result in slower reaction rates, unstable potential readings, and diminished overall performance of the cell. Wetting the salt bridge is crucial to maintain a stable flow of ions between the half-cells and facilitate efficient electron transfer.
"Water rich" and "water poor" refer to the availability and abundance of water resources in a particular area. A "water rich" region has abundant freshwater sources, such as rivers, lakes, and groundwater, supporting ecosystems and human activities. Conversely, a "water poor" area struggles with limited water availability, which can hinder agriculture, industry, and overall quality of life. This classification often highlights the disparities in water resource distribution globally.
It could mean lots of things. The usual cause for this to happen is damage to the fishes gut caused by poor water conditions and/or poor quality food. My advice is to do a few more water changes than normal and give the fish a treat of live food occasionally.
In English it means poor.
no they don't The water gets cleansed and is clean when the poor drink the water though in some countries, the poo from the lake does infect the water and then the poor drinks it.
Poor water affects humans everyday. Poor water can cause people to have parasites and become extremely ill and even die.
Guessing you mean electrical conduction. Yes, liquids can conduct electricity. Pure water is a poor conductor, water with impurities like salt water is an EXCELLENT conductor.
you mean african poor or normal poor?
This question demands a comparison - poor with regard to what?. Water is a good solvent compared with carbon dioxide. Water is a poor solvent compared with nitric acid.
If water quality is poor you must sterilize the water before you drink it or put it in food, else get water somewhere else.
Could be a bacterial infection called Popeye. Probably due to poor water quality.
