idk, why're you asking me?
you should've listened more in your chemistry class

Does alkali has a pH of over 12?
Some do. But all alkali have a pH value of more than 7.
What can tell us wether something is acid or alkali?
You can measure the pH value, if the value is below 7, then it is an acid. (1 being the strongest, 7 being neutral.) There are also some indicators, phenopthalin (think that is what is it called) which will turn purple, when poured into an acid.
What does a wash bottle containing a dilute solution of alkali does?
it can cause of PH
Is it true that when adding an acid to an alkali makes pH number go up?
A neutralization process take place.It emmits energy as heat,so temperature increase.Answer:Neutralization is often exothermic (produces heat) A typical example is is the mixing of sodium hydroxide and hydrochloric acid. However endothermic neutralization reactions (the reaction cools the solution) do happen. A simple example is the mixing of baking soda and acetic acid.
Treatment of water with chlorine is formed more HOCl at low pH is true or false?
True because it is an acid, which is, on the pH scale, pH 1-6. Once merged with water, it will lower pH to about pH 4-5; and raise substance levels.
Will the pH change when an alkali is added to an acid?
Yes. The pH will increase.
Does water change the pH level of vinegar?
no. water just dilutes the acid but the PH will not change unless an acid or alkali is added
What is the change in PH when an alkali is slowly added to an acidic solution?
The actual answer depends on the strength of the acid / alkali used. However the pH will change from around 1-6 to 8-14 depending on the strength of the acid / base. pH ~1 for strong acid pH ~6 for weak acid pH ~8 for strong base pH ~14 for strong base
Describe a solution that contains a buffer?
Acetic acid is added to the solution, but the pH of the solution does not change. Sodium hydroxide, a base, is added to the solution, but the pH of the solution does not change.
What changes in PH occurs if an alkali is slowly added to an acidic solution?
The actual answer depends on the strength of the acid / alkali used. However the pH will change from around 1-6 to 8-14 depending on the strength of the acid / base. pH ~1 for strong acid pH ~6 for weak acid pH ~8 for strong base pH ~14 for strong base
How does neutralization change the pH value of an alkali?
when an acid is neautrilized, its ph value is changed to be around 7 and it is no longer a acid
What is the difference between and acid and an alkali?
an alkali is much stronger than an acid because an acid has a PH of 1 and an alkali has a PH of 14.
What happens to pH value when alkali is added to an acid?
If you are asking about acid then the pH value will go from 7- to 7+.... If you are asking about the alkali the pH value will go from 7+ to 7-....
How does pH change when an acid is added to a base?
The pH lowers from around 14 to a lower number as acid is added.
What is the difference between an acid and an alkali?
an acid has a pH under 7 an alkali has a pH over 7
How could you titrate an acid and alkali without the use of an indicator?
If the acid or alkali forms an insoluble salt, you could titrate it that way. For instance, suppose you had a solution of sulfuric acid of unknown concentration. You could add calcium hydroxide until the precipitate stops forming and determine the strength of the acid by the amount of base added. If both the acid and alkali are soluble, a pH meter can be used to measure the change in pH of the solution. Drawing the change of pH against volume titrated will thus give the endpoint of the reaction.
How do you know pH 11 is acid?
pH 11 is an alkali not an acid
