NO!!!!
The pH scale is from 0 to 14.
The lower the numerical value of the pH , then the stronger the acid.
e.g. pH = 1 Strongly acidic ( e.g. Hydrochloric Acid).
pH = 4 Weakly acidic ( e.g. Ethanoic (Acetic) acid).
pH = 7 Neutrality (Water)
pH = 9 Weakly Alkaline ( Ammonia Solution).
pH = 12 Strongly Alkaline ( Sodium Hydroxide).
pH = 14 Very strongly alkaline ( very weakly acidic ; in extremis).
NB The pH is the 'negative logarithm , to the base 10, of the hydrogen ion conc'n. Algebraically ; pH = -(log(10)[H^(+)])
The inverse maths. function is [H^(+)] = 10^(-pH).
So if you have a pH = 1
Then H^(+) = 10^(-1) = 0.1 ( Casually a tenth of the sol'n is hydrogen ions).
If you have a pH = 12
Then H^(+) = 10^(-12) = 0.000000000001 (Casually a trillionth of the solution is hydrogen ions; usually considered as strongly alkaline with a pOH = 0.01, an hundredth of the solution is hydroxide ions, compared to a trillionth( an extremely tiny amount), of hydrogen ions.
What else can I help you with?
What is the term that describes acids which give a low concentration of hydronium ions?
Such acids are considered weak acids, such as organic acids.
What is the pka of ch3ch2sh?
The pKa of ethanethiol (CH3CH2SH) is approximately 10.5. This indicates that it is a weak acid, and the thiol group (-SH) can donate a proton in solution. Consequently, it is more acidic than alcohols but less acidic than carboxylic acids.
What are the strong and weak acids?
Strong acids are acids that dissociate readily from their hydrogen ion(s). Examples include: Strong acids HCl, hydrochloric acid HNO3, nitric acid HI, hydroiodic acid H2SO4, sulfuric acid HBr, hydrobromic acid HClO4, perchloric acid HClO3, chloric acid Weak acids do not dissociate readily from their hydrogen ions. They, therefore, act weakly as an acid. All edible acids are, naturally enough, weak acids. Examples include: Weak acids HCN, hydrocyanic acid (COOH)3C3OH, citric acid tartaric acid, lactic acid, oxalic acid ...
How long do weak tornadoes typically last?
Weak tornadoes typically last less than 5 minutes.
Can weak acids and bases react more easily with materials than do strong acids and bases?
Weak acids and bases can sometimes react more easily with certain materials due to their ability to form stable complexes or partial ionization, which allows for more controlled interactions. They may also cause less immediate damage than strong acids and bases, enabling longer exposure times without extensive degradation. However, the reactivity ultimately depends on the specific materials involved and the conditions of the reaction. Therefore, it's not a straightforward comparison; context matters significantly in determining reactivity.
Do strong acids have more or fewer ions than weak acids?
Strong acids have more ions in solution than weak acids because they completely dissociate into ions when dissolved in water, while weak acids only partially dissociate. This results in a higher concentration of ions for strong acids.
Why are weak acids better descalers than strong acids?
Weak acids are better descalers than strong acids because they are safer to handle due to their lower reactivity. Weak acids are also less likely to damage the surfaces being cleaned compared to strong acids, making them a more suitable choice for descaling tasks.Additionally, weak acids are effective at breaking down mineral deposits without causing corrosion.
What are the differences in properties and behavior between a weak acid and a strong acid?
Weak acids and strong acids differ in their properties and behavior. Weak acids partially dissociate in water, while strong acids fully dissociate. This means weak acids have lower conductivity and pH compared to strong acids. Additionally, weak acids have higher equilibrium constants and are less reactive than strong acids.
What is true about weak acids as compared to strong acids?
Weak acids have a larger value of pKa than strong acids
Does a weak acid resist a change in the pH?
NO!!! A 'Buffer Solution'., resists a change in pH. A Buffer Solution is a solution of the weak acid and its corresponding salt. e.g. Ethanoic Acid and Sodium Ethanoate. The ethanoic acid only partially dissociates in to ;_ CH3COOH < ====- > CH3COO^(-) + H^(+) The sodium ethanoate fully dissociates CH3COONa ====> CH3COO^(-) + Na^(+) If you add a small quantity of hydrogen ion H^(+), then these ion will reassociate with the 'excess' ethanoate ions from the sodium ethanoate. Thereby reducing the number of hydrogen ions in solution, hence the pH changes by only a very small amount ; it is described as 'resisting a change of pH'.
Is weak acid on the pH scale is it 3?
A acid is 6 or less A Base is more than 8 7 is neither So is it is
Is weak base on the pH scale is it 3?
any thing with a pH below 7 is an acid and anything with a pH above 7 is a base. So a weak base would be around 8
Do strong acids and bases conduct more or less electricity than weak ones?
Strong acids and bases conduct more electricity than weak ones because they ionize completely in solution, creating more charged particles that can carry electric current. Weak acids and bases only partially ionize, resulting in fewer charged particles and lower conductivity.
What is the definition of weak acid?
A weak acid is an acid that incompletely dissociates into ions in a solution, resulting in a relatively low concentration of hydrogen ions. This leads to a less acidic solution compared to strong acids. Weak acids typically have a higher pH and are less corrosive.
Is alkali an acid?
No. Alkali's and acids are an separate ends of the pH scale, the pH of acids being 1, 2, 3, 4 and 5 (strong to weak) and the pH of alkali's being 11, 12, 13, 14 and 15 (weak to strong). Examples of acids are hydrochloric acid (strong) and vinegar (weak). Toothpaste is an example of a weak alkali.
Can strong acids react more easily with materials than do weak acids and bases?
yes
Do strong acids or bases react more easily with materials than do weak acids and bases?
Strong acids and bases react more easily with materials than weak acids and bases because they completely dissociate into ions, making them more reactive. Weak acids and bases only partially dissociate, limiting their reactivity with materials.
