Why acids are useful?
Otherwise we would have nothing to neutralise alkalis with, the whole would be alkalis rather than acids and alkalis.
Do alkalis have a pH less than 7?
no they alkaline solutions have a pH higher than 7
Are alkalis stronger than acids?
Well acids are usually stronger but i guess it depends on the acid/alkali. Be careful with theses they are very corrosive and could kill you.
Are strong alkalis as dangerous as strong acids?
Strong acids and strong alkalis both tend to be very corrosive and potentially lethal if you are exposed to them. They can cause very severe chemical burns externally and internally.
What alkalis are in soap?
Soap is a product of reaction of fatty acids (present in vegetable oils and fats) and strong alkalis (NaOH or KOH). No alkali should be present in the final product - soap. If it is, this means that more alkali was used than necessary for saponification and the excess was not separated in the additional steps.

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.
Which acid does not contain H ion?
All acids contain H+ but stronger acids contain more than weaker acids. Alkalis contain OH-. In stronger alkalis there is more OH- and in weaker, there is less. This is why pH7 is neutral - the H+ and the OH- form H2O which is a neutral substance.
Is there more than one indicator that changes colour in acids or alkalis?
No, many types of color indicators are known.
Do alkalis have a pH less than 7?
no they alkaline solutions have a pH higher than 7

Fact about acid?
acids have a pH of less than 7, acid reacts with alkalis, acid turns litmus paper red. :)
Are alkalis safer than acids?
Alkali because the thin layer of grease around your skin will stop most of the acid but the alkali will eat through it and turn it into soap (that's how you make soap, mix grease with an alkali)and eat through your skin Lollz
Why do fish have more poly unsaturated fatty acids than cattle?
cattle have more unsaturatedfatty acids than fish cattle have more unsaturatedfatty acids than fish cattle have more unsaturatedfatty acids than fish cattle have more unsaturatedfatty acids than fish
Is hydrochloric acid alkali or acidic?
No - acids and alkalis are "opposites". Acids have a pH less than 7 (which is the pH of water which is neutral) and alkalis have one over 7. Sulphuric acid comes in various strengths but often has a pH less than 1 and sometimes one which is negative.
