What is the pH of an alkali?
The pH of an alkali is typically above 7 on the pH scale. Alkalis have a pH greater than 7 due to their ability to donate OH- ions in solution, making them basic substances.
What is the pH scale of the strongest Alkali?
The pH scale of the strongest alkali is typically around 14. Examples of strong alkalis include sodium hydroxide (NaOH) and potassium hydroxide (KOH), which can produce a highly alkaline solution with a pH of 14.
Is saliva an acid alkali or base?
Saliva is slightly alkaline, with a pH range of around 6.2 to 7.6. This means it tends to be more on the basic (alkaline) side of the pH scale.
What is pure water is an acid or an alkali?
Pure water is neutral, neither an acid nor an alkali. Its pH is around 7, which is considered neutral on the pH scale.
Are apples acidic alkali or neutral?
Apples juice is acidic.
Is rainfall from polluted areas an alkali?
No, it is an alkali according to the pH scale or pH indicator.
Is is soap solution strong or weak acid?
its an alkali, the other side of the pH scale you numpty;)
On what scale can we place acid and alkali according to their strengths?
The pH Scale.
What has a pH scale over 12?
A strong alkali :)
What base mean in science on the pH scale?
A soluble base is an alkali, so above 7 on the pH scale.
Is alkali or alkaline used in the pH scale?
An alkaline solution has a pH over 7,00.
What is the pH of an alkali?
The pH of an alkali is typically above 7 on the pH scale. Alkalis have a pH greater than 7 due to their ability to donate OH- ions in solution, making them basic substances.
What does a ph-scale show you?
how acidic alkali or neutral a substance is.
What is the pH scale of the strongest Alkali?
The pH scale of the strongest alkali is typically around 14. Examples of strong alkalis include sodium hydroxide (NaOH) and potassium hydroxide (KOH), which can produce a highly alkaline solution with a pH of 14.
Is saliva an acid alkali or base?
Saliva is slightly alkaline, with a pH range of around 6.2 to 7.6. This means it tends to be more on the basic (alkaline) side of the pH scale.
Why does the pH of water change after a reaction with an alkali metal?
The pH of water changes after a reaction with an alkali metal because the metal reacts with water to produce hydroxide ions, increasing the concentration of hydroxide ions in the solution and making it more basic. This leads to a shift in the pH towards the alkaline side of the pH scale.
What is pure water is an acid or an alkali?
Pure water is neutral, neither an acid nor an alkali. Its pH is around 7, which is considered neutral on the pH scale.
