What number represents a weak acid?
on a PH scale 7 is neutral. So any number close to 7 is considered weak be it a base or an acid.
What is the significance of KOH number in natural rubber latex?
It represents the tatal fatty acid present in the latex
An acid with 2 H's equals what acid?
Here's a small list of common acids. Just because it my be H2 doesnt make it a acid though. Hope this helps a little bit! Hydrochloric Acid=HCl Hydrobromic Acid=HBr Hydriodic Acid=HI Hydrofluoric Acid=HF Nitric Acid=HNO3 Sulfuric Acid=H2SO4 Perchloric Acid=HClO4 Acetic Acid=HC2H3O­2
What is the pH number ranges for bases?
acid=1-6 nuetral=7 base=8-14 the ph scale goes from 1 to 14
Who pH has a higher numerical value acids or bases?
The pH scale goes as follows : |____________|___________| 0 ACIDIC 7 BASIC 14 Below 7 = Acid More than 7 = Base
What is pH number of strong acid?
A number less than a pH of 4 indicates a strong acid.
What should be pH -value to be strong acid?
The pH will depend on the concentration of the acid, not on whether it is strong or weak.
What should be pH value to be strong acid?
The pH will depend on the concentration of the acid, not on whether it is strong or weak.
Is benzene sulfonic acid a weak acid?
It is a strong organic acid with a pka value of -2.8 very similiar to sulfuric acid at -3.
What is the Literature ka value of salicylic acid?
Salicylic acid is also known as 2-Hydroxybenzoic acid. The literature Ka value is 2x10 to the negative 14th power. Which makes salicylic acid a somewhat strong acid.
What value on the pH scale represents a strong acid a strong base and a neutral substance?
Strong acid = 1 pH ( or lower ) Strong base = 14 pH ( or higher ) Neutral solution = 7 pH
What is pH of a strong acid and pH of a weak acid?
A strong acid id PH 1 or 2 and a weak acid is a number between 5 or 6 Not 7 because that is neutral
What is the pKa value for Hydroastatic acid and Periodic acid?
There are no accurate pKa value of these two, extremely STRONG acids, any value of >> 1000 (up to >> 1.0*10+9) will do.
What makes an acid stronger than the other?
The difference is between dissociation constants. A high value has the meaning of strong acid.
What is the ka value for sulfamic acid?
According to CRC reference data, the pKa of sulfamic acid is 1.05, giving a Ka of 11.2. This is a strong acid.
Is sulfurous acid strong or weak acid?
H2SO3, or sulfurous acid, is weak. A quick way to verify the strength of acids with oxygen in them is to get the number of oxygen atoms (in this case, 3) minus the number of hydrogen atoms (in this case, 2); if the result is lower than 2, the acid is weak.
When a buffer system forms a weak acid from a strong acid what happens to the PH?
The pH number will be higher
