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
Is pH12 a strong acid?
No, pH 12 indicates a strong base, not a strong acid. A strong acid would have a pH value below 7.
What is pH number of strong acid?
A number less than a pH of 4 indicates a strong acid.
What value on the pH scale represents a strong acid a strong base and a neutral substance?
A strong acid has a pH value close to 0, a strong base has a pH value close to 14, and a neutral substance has a pH value of 7.
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 hydroiodic acid a weak acid?
Hydroiodic acid is a strong acid, meaning it completely dissociates into ions when dissolved in water. It has a high degree of ionization and a low pKa value, indicating its strength as an acid.
Why is nitric acid classified as a strong acid?
Nitric acid is classified as a strong acid because it completely dissociates in water to produce a high concentration of hydrogen ions. This leads to a low pH value in solution, making it a strong acid.
Which acid is stronger vinegar H2So4 NaOH?
Sulfuric acid (H2SO4) is stronger than vinegar (acetic acid) and sodium hydroxide (NaOH). Sulfuric acid is a strong acid with a low pH value, while vinegar is a weak acid with a higher pH value. Sodium hydroxide is a strong base.
How do Ka values of weak acid and a strong acid compare?
The Ka value of a weak acid is smaller than the Ka value of a strong acid because weak acids only partially dissociate in solution, resulting in lower concentrations of H+ ions. Strong acids like hydrochloric acid (HCl) completely dissociate in solution, leading to higher concentrations of H+ ions and therefore a larger Ka value.
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 is the pKa value for Hydroastatic acid and Periodic acid?
The pKa value for hydroastatic acid (H2AstO4) is approximately 7.2. The pKa value for periodic acid (H5IO6) is around 1.74.
What is the pH of hyrdochloric acid?
The pH of hydrochloric acid is approximately 0, making it a strong acid.
