What is common in Benedict solution and Fehling solutions?
Both are Cupric ( Cu-II ) alkaline complex-ion solutions
What is the ion responsible for the alkaline property of sodium hydroxide?
This is the ion hydroxyl, OH-
If the hydrogen ion concentration of a solution is 10-10M is the solution acidic alkaline or neutral?
Alkaline
Is fluoride an acidic or alkali?
The fluoride ion is alkaline
What is the pH factor?
In chemistry, pH is a measure of the activity of the hydrogen ion. Pure water has a pH very close to 7 at 25°C. Solutions with a pH less than 7 are said to be acidic and solutions with a pH greater than 7 are basic or alkaline.
Is bicarbonate acidic?
No. The bicarbonate ion is generally basic (alkaline)
Is there An alkaline solution which has no metallic ion?
Ammonia dissolves in water to form ammonium hydoxide, not a meetallic ion in sight!
Does an alkaline earth metal element form an ion with a charge of -1?
Alkaline earth metals form cations withe the electrical charge +2.As an exceptional curiosity exist the ion Ca-.
What are the reasons or ways something could have a high pH level?
A basic or alkaline solution is the term used for solutions having a pH above 7. Increasing the hydronium ion (OH-) concentration of the solution will increase the pH.
What alkali does bleach contain?
An alkali is a soluble base. Therefore, alkaline solutions are sources of hydroxide ions, OH- . A base is a proton acceptor, so the alkaline solution will neutralise an acid.
Are metals alkaline?
Yes When metals react with water they produce a metal hydroxide, this contains an OH- ion (which accepts protons and is therefore alkaline) This makes all metals alkaline.
What are solutions that have more OH- than H ions?
An arrhenius acid is, by definition, a solution with a higher concentration of H+ ion than OH-. So any arrhenius acid will fit this definition. Two common acids are Lemon juice and vinegar.
