Do alkalis have a pH less than 7?
no they alkaline solutions have a pH higher than 7
Are alkalis and acids dangerous?
Alkalis and acids can be dangerous if handled improperly. They can cause burns, irritation, and other harmful effects if they come into contact with skin, eyes, or other tissues. It is important to use appropriate precautions when working with alkalis and acids to prevent accidents and injuries.
Why are alkalis the opposite of acids?
Alkalis are substances that produce hydroxide ions (OH-) in solution, while acids produce hydrogen ions (H+). When an acid reacts with an alkali, they neutralize each other forming water and a salt, which is why they are considered opposites in terms of their chemical properties. Acids have a pH below 7, while alkalis have a pH above 7 on the pH scale.
What is pH value of alkali?
The pH value of alkali substances is typically above 7, indicating that they are basic. Alkalis have a pH value greater than 7 but less than 14. Examples of alkalis include ammonia, sodium hydroxide, and potassium hydroxide.
What is the difference between and acid and an alkali?
Acids are substances that donate protons in a chemical reaction, while alkalis are substances that accept protons. Acids have a pH value below 7, whereas alkalis have a pH value above 7. Acids tend to taste sour, while alkalis tend to taste bitter.
How can you tell how strong acids and alkalis are using the pH scale?
Acids have a pH under 7, alkalis have a pH bigger than 7.
What colours does ph paper turn in alkalis?
pH paper turns blue or purple in alkalis.
Weakest alkalis have a pH of?

Do alkalis have a pH less than 7?

What makes alkalis alkalis?
Look on the pH scale. Below 7 are acids, above 7 are alkali's!! ;-)
Alkalis have a pH what than 7?
great then 7
List four properties of alkalis?
alkalis are corrosive, normally water soluble and are very soapy.
Are alkalis and acids dangerous?

What is the pH range of solutions which are alkalis?
Alkalines, or bases, have a pH greater than 7 (maximum is 14).
Does Neutral mean safe?
Not really. On the pH scale of Acids and Alkalis, Neutral is the green colour at which a liquid is neither Acid nor Alkalis.
