What else can I help you with?
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.
Do alkalis have a pH less than 7?
no they alkaline solutions have a pH higher 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?
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.
What is the pH range of solutions which are alkalis?
Alkalines, or bases, have a pH greater than 7 (maximum is 14).
What solutions is the weakest acid pH of 2.4 pH of 5.2 pH of 6.4 pH of 8.6 or pH of 10.1?
pH=6,4
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.
What pH do Alkalis have?
Any aqueous solution that has a pH value greater than 7 can be considered alkaline. A strongly alkaline aqueous solution usually has a pH of at least 10, and aqueous solutions of very strong alkalies can have a pH range above 13.
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.
