Is pure water is alkali?
No,pure water is not alkali.Pure water is neutral.
What are the reactions with alkali metals and water like?
1) Alkali metals are stored in oil to minimise reaction with oxygen or water, it's a physical barrier towards air but the alkali metals still gradually corrode a traces of oxygen and water diffuse through. The reaction of alkali metals with water gets more violent for elements lower in the group e.g. (Li < Na < K < Rb < Cs). Adding them to water will cause an explosion due to the extremely exothermic nature of reaction, and can be rather dangerous and some alkali metals can react violently with just moisture in the air. Most of the alkali metals float on the top of the water, depending on how big the alkali metal is determines the size of the reaction this is because they're less dense that water itself and also during the reaction the alkali metals give of hydrogen gas which is quite flammable. Alkali Metal + Water » Metallic Hydroxide + Hydrogen The francium would be like any other alkali metal, it would be very violent like the other alkali metals.
What removes uric acid and salts from the hemolymph?
it is dissolved in water
An aquatic environments water blank refers to the amount of dissolved salts nutrient's and oxygen in the water?
An aquatic environment's water CHEMISTRY refers to the amount of dissolved salts, nutrients, and oxygen in the water. If you are in Mr. Sarau's class...nice going. haha
What substances are called that are not acid or alkali?
It is a neutral substances.Examples are water,methane etc.
When 2.61 of solid Na2CO3 is dissolved is sufficient water to make 250 mL of solution the concentration of Na2CO3 is?
You need to mention the unit for 2,61.
What are acids alkali and neutral?
Chemicals that release the H+ ion when dissolved in water are acids. Chemicals that release the OH- ion when dissolved in water are alkali (also known as bases) and water is neutral.
Is ammonia alkali?
Amonia is an alkaline gas. However, when dissolved in water it form an alkaline solution (alkali).
What ion is produced when any alkali is dissolved in water?
This is the hydroxyl ion OH-.
Can you give an example of a combustion with no flame?
When alkali metals react with water it will explode. Potassium dissolved in water and rubidium and cesium very highly reactive metals dissolved in water will create combustion. Search brainiac alkali metals on youtube.com and see for your self.
How are 0.50 mol Na2CO3 and 0.50M Na2CO3 different?
0.5 mol of Na2CO2 is the ACTUAL dry crystal amount. 0.5 M 0f Na2CO3 means that o.5 moles has been dissolved in 1 litre of water. The M means ' moles per litre(dm^3)'.
How much alkali is there in hair gel?
there is 9 % of an alkali in hair gel and the rest is water . the alkali in it is what makes it sticky.
Does acid and alkali equal salt water?
Sea water is in fact basic. This results from the various salts dissolved in the water. Although one would expect sea water to be acidic (carbon dioxide from the air dissolves in water to form carbonic acid), limestone deposits help to keep the ocean basic.
How do you neutralize a acid or alkali?
To neutralise an acid add sodium carbonate. 2H^+ + Na2CO3 = 2Na^(+) + H2O + CO2 It forms the salt , water and carbon dioxide. To neutralise an alkali add 'milk'.
What is the difference between alkali and alkaline?
Alkali stands for a chemical compound that neutralizes with acid and turns litmus blue and release hydroxide ions when dissolved in water. Alkaline has the properties of alkali or containing alkali and having pH greater than 7.
Would an acid or an alkali be formed if an oxide were dissolved in water?
When you dissolve an Oxide (e.g. CO2 or SO2) in water you normally make an acid.
Are all alkalis dissolved in water?
Alkalies are those bases which are completely water soluble, so alkali can not be water insoluble.
