HCl is an acid. The hydrogen part of the molecule makes it so. A pH below 7 is acidic and a pH above 7 is basic. It makes sense that adding an acid to water would lower the pH.

How fast can urine drop in temperature?

Urine can drop in temperature fairly quickly after leaving the body, especially in colder environments. However, the rate of temperature decrease can vary depending on factors like the initial temperature of the urine, the ambient temperature, and whether the urine is contained or spread out.


How fast will liquid nitrogen freeze 1 cubic foot of ocean water when added directly to it?

The time it takes for liquid nitrogen to freeze 1 cubic foot of ocean water would depend on various factors including the initial temperature of the ocean water, the volume of liquid nitrogen added, and the surrounding conditions. Typically, liquid nitrogen is extremely cold at around -320°F and would quickly freeze the water upon contact.


Does the salinty leval effect how fast ice melts?

Yes, the higher the salinity level of water, the slower ice will melt because salt lowers the freezing point of water. This means that salty water must be colder than fresh water in order for ice to remain frozen.


How fast does your blood alcohol level drop?

On average, your blood alcohol level drops by about 0.015 grams per deciliter (g/dL) per hour once you stop drinking. Factors like body weight, metabolism, and food consumption can affect this rate. It usually takes several hours for your blood alcohol level to return to zero.


When calcium metal is added to water the gas evolved doesn't catch fireBut the same gas evolved on adding sodium metal to watar catches firewhy it so?

The gas evolved when calcium is added to water is hydrogen gas, which does not catch fire on its own. However, when sodium is added to water, it reacts more vigorously to produce hydrogen gas, which can ignite due to the heat released during the reaction. Sodium is more reactive than calcium, leading to a more exothermic reaction that can ignite the hydrogen gas.

Why does the water level drop fast in a freestanding hot tub when it is very cold outside?

When it's cold outside, the air temperature causes the water in the hot tub to evaporate more quickly. As the water evaporates, the water level drops faster. This is because cold air is less humid than warm air, leading to increased evaporation.


Why does ice melt faster in soda than in water?

Each liquid has a different melting and boiling point. If you place ice (frozen water) into a glass of water, then the water's temperature can only drop to 32 degrees and it will begin to melt. If you drop ice (pure frozen water) into Sea Water(water with salt), then the Sea Water can drop below 32 degrees. So it will take longer for the ice to warm up enough to melt. It has to do with the freezing point of the liquid it is in.


How do you get 60 fast?

I've heard Iron is really fast XP and cash. I recommend drop-mining iron. Mine iron, then drop it instead of selling it. However, if you also want the money, just sell it - but getting your mining level up will then take a bit longer.


How fast does water boil at sea level?

Water boils at 100 degrees Celsius (212 degrees Fahrenheit) at sea level.

Would a stick float?

no because the way the drops to the ground it drops fast ,so when you think about it if you drop it in the water you should know that it will sink

How can you capture the perfect moment of a water drop splash in a photograph?

To capture the perfect moment of a water drop splash in a photograph, use a fast shutter speed to freeze the motion of the drop as it hits the water surface. Adjust the lighting to highlight the details of the splash and use a macro lens to capture the intricate patterns created by the water droplets. Experiment with different angles and compositions to create a visually striking image.


How fast does half a stick of chalk dissolve in water?

In order to dissolve chalk in water, vinegar needs to be added. The vinegar has acid in it that eats away at the chalk to dissolve it.
