maybe a dust that is really strong.
red
it is weak and strong because it neutralises acids. So its strong not weak but weak not strong.
due to its behaviours of complexes crown ethers they act as strong phase transfer catalyst.
Color centers in alkali halides are defects in the crystal lattice that result from the absence of an alkali metal atom or halide ion, leading to the creation of an electron trap or vacancy. These defects can absorb specific wavelengths of light, resulting in the coloration of the material. Common examples include the F-center, which forms when an electron occupies a vacancy left by a halide ion, imparting a characteristic color to the crystal. The presence and type of color centers can significantly influence the optical properties of the alkali halide.
No. Alkali's and acids are an separate ends of the pH scale, the pH of acids being 1, 2, 3, 4 and 5 (strong to weak) and the pH of alkali's being 11, 12, 13, 14 and 15 (weak to strong). Examples of acids are hydrochloric acid (strong) and vinegar (weak). Toothpaste is an example of a weak alkali.
A strong alkali typically has a pH value higher than 12. Examples of strong alkalis include sodium hydroxide (pH around 14) and potassium hydroxide (pH around 14). These substances are highly caustic and can cause severe burns.
you create a neutral solution -------------------------------------------------------------------------------------------- Well it depends actually it doesn't always create a neutral solution. Here's the order: Strong Alkali + Strong Acid = Neutralisation (water + salt) Strong Alkali + Weak Acid = Weak Alkali Weak Alkali + Weak Acid = Neutralisation ( water + salt) Weak Alkali + Strong Acid = Weak Acid Strong Alkali + Strong Acid = Neutralisation (water + salt) Hope it helps! :)
Paper is not an alkali; it is a material made from wood pulp. Alkalis are typically strong bases, with substances like sodium hydroxide and potassium hydroxide being common examples. Paper is neutral in nature and does not exhibit the properties of an alkali.
The examples of the alkali are the washing products, soap, shampoo, and the washing up liquids.
ph 8- p14 is a alkali. blue for weak alkali (ph 8) purple for strong alkali (ph14)
Strong
any concerted alkali is weak alkali
No.
Universal indicator would be dark blue or purple in a strong alkali.
Yes, it can corrode your skin and tissue. So if you get a strong alkali on you, wash it of as quick as possible, even if it is on your clothes.
Universal indicator turns deep blue or violet when mixed with a strong alkali.
