What is used to detect the presence of an acid or alkali?
A universal indicator is commonly used to detect the presence of an acid or alkali. It changes color based on the acidity or alkalinity of a solution, helping to identify whether a substance is acidic, neutral, or alkaline.
What turns red in the presence of acid and blue presence of alkali?
A red litmus paper turns blue in the presence of a base/alkali, while a blue litmus paper turns red in the presence of an acid.
How can you detect the alkali in the water at the end of the reaction of potassium with water?
One way to detect the alkali in water after the reaction of potassium is by using a pH indicator paper, which will turn a specific color in the presence of alkali. Another method is to perform a simple acid-base titration using an acid solution of known concentration and an indicator to determine the amount of alkali present in the water.
What turns red in the presence of acid ad blue in the presence of alkali?
You probably mean litmus paper. (see https://en.wikipedia.org/wiki/Litmus.)
What green liquid is used to determine if a chemical is a acid or alkali?
A green liquid called phenolphthalein is commonly used to determine if a chemical is an acid or alkali. Typically, it turns pink in the presence of a base (alkali) and remains colorless in the presence of an acid.

Litmus Paper.
What is the colour of litmus paper?
Red/blue red turns to blue to detect alkali blue turns to red to detect acid
What is rust acid or alkali?
Rust is formed when iron reacts with oxygen in the presence of moisture, creating iron oxide. It is not an acid or an alkali but a chemical compound known as iron oxide.
Is cream and alkali an acid or neutral?
Cream is slightly acidic due to the presence of lactic acid from fermentation. An alkali is a base, which is the opposite of an acid on the pH scale. When cream is mixed with an alkali, the pH may shift towards neutral depending on the specific alkali used and the overall ratio of the mixture.
What color does onion skin turn in acid and alkali?
Onion skin turns red in acid and green in alkali due to the presence of anthocyanin pigments that change color based on the pH of the solution.
Is hot chilli sauce an acid or an alkali?
Hot chili sauce is typically acidic due to the presence of ingredients like vinegar or citrus juices.
