How are Alkaline metals compared to alkali metals?
alkali metals are the "mad" elements who explode when exposed to a certain element. for example, sodium cannot be exposed to hydrogen, or it will explode. on the other hand, alkaline earth metals are good conductors, but they do not explode. they also come only from the earth and its crust.
What changes do you expect to see when the cells are exposed to the solution?
trying to figure this out 2!!
What metal could explode if you reacted it with an acid?
All the alkaline metals will explode violently when exposed to H2O. The further down you go on the Periodic Table of the elements, the more reactive they become.(Hope this helps!)
Is magnesium an acid or a base?
It is a metal. Exposed to the atmosphere where water and oxygen are present will produce quite an alkaline material close to pH 12, a strong base.
What is hypotonic solution?
A hypotonic solution has a lower solute concentration compared to the cells it surrounds. When cells are exposed to a hypotonic solution, water will move into the cells through osmosis, causing them to swell or potentially burst.
What is the name given to a dye that changes colour depending on whether it's an acid or alkaline?
A dye that changes color depending on whether it's exposed to an acid or alkaline solution is called a pH indicator. pH indicators are commonly used in chemistry labs to determine the acidity or alkalinity of a solution based on the color change they undergo.
Why does Litmus Paper change blue?
Litmus paper turns blue when it is exposed to a basic (alkaline) solution, indicating a pH level greater than 7. This color change occurs due to a chemical reaction between the alkaline solution and the dye present in the litmus paper.
Will polyester bleach if exposed to bleach solution?
Polyester will not bleach if exposed to a bleach solution.
What is the color of pH strip when the water has a 9.5 pH level?
The color of a pH strip will vary from red to violet when exposed to either an acidic or alkaline solution. Water with a pH level of 9.5 is more alkaline and would show up as blue in color.
What is meant by term alkaline error?
Alkaline Error: A systematic error that occurs when glass electrodes are used to read the pH of an extremely alkaline solution; the electrode responds to sodium ions as though they were hydrogen ions, giving a pH reading that is consistently too low.
Is rust alkaline?
No, rust is not alkaline. Rust is a reddish-brown oxide that forms on iron or steel when exposed to oxygen and moisture. It is a chemical compound known as iron oxide.
Why does phenolphthalein change color in alkaline pH?
Phenolphthalein is a compound with chemical formula of C20 H14 O4. It is colorless but turns pink in alkaline solutions. This is because it undergoes a process of ionization where positively or negatively charged ions are added or removed from a molecule, which converts the molecule into ions. Phenolphthalein molecule contains positively charged hydrogen ions and is naturally colorless with bright pink ions. When exposed to an alkaline solution, these hydrogen ions are removed, phenolphthalein molecule gets ionized and the solution turns pink. The stronger is the alkali solution, more hydrogen ions removed and stronger pink colour of the phenolphthalein solution.
What is the substance that turns litmus blue?
A base/alkali substance will turn litmus paper blue.
What happens when francium and cesium are exposed to water?
When francium and cesium are exposed to water, they react vigorously, producing hydrogen gas and forming a strongly alkaline solution of the respective hydroxides. Francium is highly radioactive and rare, while cesium is more commonly used in various applications due to its lower reactivity and availability.

Why does crushing solute increases the rate of solution?
More surface area is exposed.
