Both ammonia and water exhibit hydrogen bonding. This is an intermolecular force that holds molecules together to increase their melting and boiling points. Water is a small molecule and really should be a gas at room temperature if you compare it to its nearest chemical relative, hydrogen sulfide. Water is not a gas, thank goodness, but a liquid due to hydrogen bonding.
Hydrogen bonding is the interaction of a slightly positively charged hydrogen nucleus with a neighboring slightly negatively charged small electronegative atom like nitrogen, oxygen or fluorine.
Ammonia, NH3 and water, H2O both have higher melting points due to hydrogen bonding. In chemistry the general rule is the bigger the molecule the higher its melting point.
Ammonia melts at -77oC whereas its bigger relative phosphorus trihydride, PH3, melts at a lower temperature of -133oC.
Similarly, water melts at 0oC but rotten egg gas, H2S, melts at -82oC.
Both ammonia and water owe their unusually high melting and boiling points to hydrogen bonding.
Another similarity between them is that both nitrogen and oxygen have electrons in their outer energy level that are not used to make a bond in water and ammonia. These are called lone pairs or non bonding pairs. Oxygen has two non bonding pairs and nitrogen has one non bonding pairs. This makes both water and ammonia attractive to hydrogen ions, H+(also called protons).

What is the standard test for ammonia gas?
Ammonia gas can be tested in these ways:1. It has a pungent smell2. It turns MOIST red litmus paper blue3. Test its alkalinity in water (pH ~ 11)4. It will extinguish a lighted splint5. It will easily dissolve in water
What is the reaction mechanism of phenol into aniline?
Phenol is converted to aniline via the Zinin reduction reaction, which involves the reaction of phenol with ammonia and sodium metal. The phenol first forms a sodium phenoxide intermediate, which reacts with ammonia to give an amine salt. Finally, the amine salt is then reduced by sodium metal to produce aniline.
WHO found a way to separate salt elements?
Lol i dont know
What are some fun and educational ways to teach kids about the properties of salt through a hands-on salt experiment?
One fun and educational way to teach kids about the properties of salt is through a hands-on salt experiment. You can create a simple experiment where kids can observe how salt affects the freezing point of water. By mixing salt with ice in a container, kids can see how the salt lowers the freezing point of the ice, causing it to melt. This can help them understand the concept of how salt is used to melt ice on roads in the winter. Additionally, you can also demonstrate how salt can change the density of water by creating a saltwater solution and comparing it to regular water. This hands-on approach can make learning about the properties of salt more engaging and memorable for kids.
What are 3 ways you could determine in the lab if a solution had salt dissolved in it without tasting?
You could use a conductivity meter to test for the presence of ions in the solution, perform a flame test to observe characteristic colors produced when salt is burned, or use a pH indicator to detect a change in pH level caused by the presence of salt ions.
Which ways are city-states alike?
They had a defensively-walled city with a hill-fortress refuge, a tract of agricultural land to provide foodstuffs, a river for water, and usually a port and salt-water fishery.
is salt necessary to treat water?
Salt is not necessary to treat water. There are many ways to treat water. Salt is not necessary because salt contains sodium. Sodium is good for treating water but is not necessary.
What is the simple way to remove blood from white cloths?
There are a few ways to remove blood from cloths. A few of these ways include soaking in cold water or using specialist liquids that are designed to remove blood. Other effective treatments include using baking soda,ammonia and salt.
What are some ways that salt water can be used to create fresh water for human use?
Salt water can be distilled, either by boiling it, or by evaporation in sunlight.
How are scientists turning salt water into fresh water?
they boil water then collect the steam in different ways
What two ways can salt be removed from salt water?
- by the evaporation of water crystallized sodium chloride is obtained - by distillation of water sodium chloride is obtained as a residual product
When ammonia occurs in water solution what ion does it form?
When ammonia (NH3) occurs in water solution, it forms the ammonium ion (NH4+). This is due to the reaction between ammonia and water molecules, resulting in the formation of ammonium ions and hydroxide ions.
What do they do after salt is separated from water?
The salt crystals can be gathered and used in a variety of ways. Personally, I like salt on my fish and chips, here in the UK!
What are two ways of obtaining salt in the Sahara desert?
One way was to dig holes in the ground, pour salt water in it, and evaporating the water, leaving the salt behind. The second way was to mine for them from the salt mine in taghaza
In what ways are addition and multiplication alike?
Multiplication by an integer is the same as repeated addition.
Do you no of any ways of extracting salt from water without using distilation?
---- yes, i do, if you evaporate the water you leve behind the salt. this is a simple yet effective way of the separation.
How does fresh water become salt water?
Water is already water so when water goes with water it becomes water then you add salt and water and it becomes salt water so you take your salt water and take your water in the water and mix the water in the water with the salt water it becomes the water in the water with salt water
