There will be a squeaky pop and the splint will go out because hydrogen has been produced

Does an acidic solution have a pH solution above 7?
No, any solution with a pH over 7 is alkaline.
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.
When pH value of a solution is 7 then what is the nature of that solution?
If the pH value of a solution is 7 then the solution is basic. Anything below 7 is considered acidic and anything above 7 is considered alkaline or basic.
How you can tell the difference between an acid and an alkali?
The pH of an acidic solution is under 7; the solution contain cations H+. The pH of an alkaline solution is above 7; the solution contain anions OH-.
Do some alkaline have a pH greater then 9?
Yes. Some alkalis do have a pH above 9. e.g. 46% NaOH solution.
Does an acidic solution have a pH solution above 7?
No, any solution with a pH over 7 is alkaline.
Is a solution with a high pH acidic or basic?
none of them is basic...solution with ph2 is more acidic than ph3 solution.
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.
Which group above 9-12 reacts with water to yield alkaline solution?
These are the alkali metals.
What kind of solution has a pH above 7 and what kind has a pH below 7?
pH above 7 = a base or alkaline solutionpH below 7 = acid or acidic solution
What types of substances tend to be alkaline?
Generally, inorganic compounds known as hydroxides, such as sodium hydroxide, are alkaline (have a pH above 7 in solution). Any compound which has such a pH in solution can be considered alkaline.
Is higher alkaline level above pH 7 caustic?
Yes, pH above 7 is the result of a more alkaline, caustic solution. It means that there's more hydroxide ions than hydroxonium ions (or protons) in this.
When pH value of a solution is 7 then what is the nature of that solution?
If the pH value of a solution is 7 then the solution is basic. Anything below 7 is considered acidic and anything above 7 is considered alkaline or basic.
How you can tell the difference between an acid and an alkali?
The pH of an acidic solution is under 7; the solution contain cations H+. The pH of an alkaline solution is above 7; the solution contain anions OH-.
How can pH of a solution be tested?
By dissolving the pH solution a colour change will occur in the solution that should be tested.Compairing the colour of solution to the colours marked on of pH chart we can find out if the solution we tested is of alkaline nature or of acidic nature or neutral.Solutions of pH7are neutral solutions.Solutions below pH7 are acidic solutions and those above pH7 are alkaline solutions.
Do some alkaline have a pH greater then 9?
Yes. Some alkalis do have a pH above 9. e.g. 46% NaOH solution.
Why glass electrode cannot be used for solution of Ph above 9?
This is because of alkaline error above pH of 9. Alkaline Error is a systematic error that occurs when glass electrodes are used to read the pH of an extremely alkaline solution (pH above 9); the electrode responds to sodium ions as though they were hydrogen ions, giving a pH reading that is consistently too low. However it is now possible to purchase [H electrodes made from special glass that can be used above pH 9.
