What is indicat?
Universal indicator changes colour in acids and alkalis. Its colour shows the strength of an acid or alkali. strong acid= redweak acid= orange / yellowneutral= greenweak alkali= turquoise / bluestrong alkali= deep blue / purple The strength of an acid or alkali is shown on the pH scale of numbers.

What happens to the pH when an alkali is added to a acid?
When an alkali is added to an acid, the pH increases as the acid is neutralized by the base. This reaction forms water and a salt. The pH ultimately depends on the strength of the acid and the alkali.
What is the difference of litmus paper and a pH paper?
pH.paper tells the strength of an acid and alkali and litmus paper tells that whether the substance is an acid or an alkali.
How can you tell if a colourless liquid is an acid or an alkali?
For an acid, the solution remains colourless or unchanged. For an alkali, it would turn fuschia.
Is alkali stronger than acid?
Alkalis are typically considered to be strong bases, which can be equally or more corrosive and harmful than acids. The strength of an alkali or acid is determined by its pH level and concentration.
What is the change in PH when an alkali is slowly added to an acidic solution?
The actual answer depends on the strength of the acid / alkali used. However the pH will change from around 1-6 to 8-14 depending on the strength of the acid / base. pH ~1 for strong acid pH ~6 for weak acid pH ~8 for strong base pH ~14 for strong base
What is the anti-acid alkali fabric?
Anti-acid alkali fabric:The anti-acid alkali fabric is widely used for preventing the harmful of acid and alkali and extend the time of acid penetration into the skin from the surface of a garment and no surface adhesion. And after acid erosion, the strength of the garment changed little and can sustain the high acid fracturing.The anti-acid alkali fabric is widely used for preventing the harmful of acid and alkali and extend the time of acid penetration into the skin from the surface of a garment and no surface adhesion. And after acid erosion, the strength of the garment changed little and can sustain the high acid fracturing.The anti-acid alkali fabric is breathable and can protect the acid-alkali and oil liquid for a long time and have the good anti-acid alkali property, which protect the workers very well and can pass the EN 13034.The classification of the anti-acid alkali fabric:1. The normal anti-acid alkali fabric: add the anti acid alkali treatment when producing the fabric, it is similar to the normal fabric and suitable to the normal acid alkali environment.2. Severe anti-acid alkali: cotted on the normal anti-acid alkali fabric. After coated, the fabric have strong property of anti-acid alkali fabric and can be suitable to the high density anti-acid alkali environment.The anti-acid alkali fabric manufacture by Xinxiang Yulong Textile is the poly cotton blended and the 100% natural synthetic fiber with the anti-acid alkali treated. It conquer the old rubber or plastic's air proof, heavy and the uncomfortable and very suitable for the light and middle acid alkali environment.The fabric can protect the acid-alkali harmful to the body and have the property of long time anti acid and high anti acid pressure and suitable for the workers under the acid alkali environment for a long time. The quantity and protective property can meet the requirement of GB 12012 and the EN 14325, EN 13034, EN 368.
