This refers to the pH of something. pH ranges from 0-14 with 7 being neutral. <7 is considered acidic and >7 is considered basic or alkaline.
acid
Sulphonate as it is from the Sulphyde group.
water is responsible for ionization of acid and base, without water the terms acid and base are meaningless.
pH scale is used to measure the strength of an acid or a base. It ranges from 0 to 14, with a lower number indicating a stronger acid and a higher number indicating a stronger base. A pH of 7 is considered neutral.
Yes, the onion olfactory indicator changes smell in both acid and base solutions. In acidic solutions, the smell becomes sharper and more pungent, while in basic solutions, the smell becomes sweeter and less intense.
When a weak acid and a strong base are mixed together, the pH of the resulting solution will be greater than 7, indicating that it is basic.
Water is classified as a neutral substance. It has a pH of 7, which is right in the middle of the pH scale, indicating it is neither an acid nor a base.
pH numbers below 7 indicate an acid, with lower numbers indicating stronger acids. pH numbers above 7 indicate a base, with higher numbers indicating stronger bases.
When an onion is cut, its cells release enzymes that break down sulfur compounds into volatile molecules that give it its characteristic smell. In an acidic environment, these sulfur compounds may become more stable and less volatile, leading to a milder smell. In a basic environment, the enzymes responsible for breaking down these compounds may be inhibited, resulting in a stronger smell.
The endpoint of an acid-base titration is the point at which the indicator changes color or the pH meter reads a significant change in pH, indicating that the reaction between the acid and base is complete. This point signifies that the equivalence point has been reached, where the moles of acid and base have reacted in stoichiometric proportions.
Litmus paper would turn red in the presence of hydrochloric acid, indicating acidity.
If liquid detergent turns red litmus paper blue, it is likely a base. Red litmus paper turns blue in the presence of a base, indicating that the detergent is causing a basic reaction.
