What else can I help you with?
What does alkali mean when its in water?
i am in the air force and this will help you pass a tets it mean sgooy
When is alkali used to calm a acid?
Neutralize, you mean :) An equal amount of an acid and an alkali will neutralize to produce water and a corresponding salt. ;)
What solution would alkali and acid give if added together?
It would depend on which acid and alkali were involved, the general rule is that adding an acid to an alkali will produce a salt and water. Sulphuric acid and sodium hydroxide would give sodium sulphate + water Hydrochloric acid and potassium carbonate would give potassium chloride and water and carbon dioxide etc
Is distilled water an alkali?
No, an alkali is a type of metal.
What substance reacts with water to give a solution of pH value greater than 7?
For example an alkali metal.
When an alkali metal reacts with water it produces what?
When an alkali metal reacts with water, it produces an alkali metal hydroxide and hydrogen gas. This is a highly exothermic reaction, with the alkali metal displacing hydrogen from the water molecule.
The word equation for the reaction of alkali metals with water?
Alkali Metal + Water ------> Alkali Hydroxide + Hydrogen Alkali Metal Oxide + Water ------> Alkali Hydroxide + Water Example: ================ Sodium + Water ------> Sodium Hydroxide + Hydrogen 2 Na + 2 H2O --------> 2 NaOH + H2
How do alkali metals react to cold water?
alkali metals react violently in cold water
What alkali metals are insoluble?
Unfortunately, we must also address the matter of ambiguous terminology. Alkali may mean the alkali metals, lithium, sodium, potassium, etc. It may also mean the high pH (alkaline) compounds such as sodium hydroxide, potassium hydroxide (lye), etc, characteristic of compounds of alkali metals.
What is the solubility of alkali metals in water?
The solubility of alkali metals in water is high. Alkali metals such as lithium, sodium, and potassium readily dissolve in water to form alkaline solutions.
What is a dilute alkali mean?
A dilute alkali refers to a solution containing a small concentration of a base or alkali substance, such as sodium hydroxide or potassium hydroxide, dissolved in water. The term "dilute" indicates that the concentration of the base in the solution is relatively low.
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.
