What else can I help you with?
What is the reaction called when an alkali cancels out an acid?
It is neutralization, say you have a wasp sting which is alkali, if you put lemon juice on it it would cancel the alkali out making the pain go away. From Nik (btw im only 13)
How would you examine the reaction of an alkali metal?
Hook up the positive lead to a 9V battery to the metal and stick the negative lead in a solution of salt water. then put the metal in the solution. this is called a corrosion cell and by hooking a battery up to it you are accelerating the process.
What can be said about the number of ions in water compared to an acid or alkali?
Pure water would have fewer ions.
Would high pH water weather limestone?
From what I know, limestone is alkali, and high pH water would not weather alkali things. For the case of limestone, it might even make the limestone bigger (think so).
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
What would an alkali do to an acid stomach?
It would tend to neutralize it and to form water plus some salt.
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.
How would you obtain an alkali from a base?
An alkali can be obtained from a base by adding water to the base. The resulting solution will have a pH greater than 7, indicating the presence of an alkali. Examples include sodium hydroxide (base) forming sodium hydroxide solution (alkali) when dissolved in water.
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.
What types of reactions would be most useful in characterizing the alkali metals?
For example the reaction with water.
If you add alkali to water what colour would the water be?
Alkalis are bases dissolved in water. They do not have specific colours and are often colourless liquids.Indicators are used to determine the strength of an acid or alkali and change colour when exposed to the liquid.Look at Universal Indicator Solution.
Does silver explode when it touches water?
Silver wouldn't explode at all in water! Unless it were the alkali/alkaline earth metals they would.
