Is HPO42 an acid or base?
H2P04– is an acid and when it is in water it forms a hydronium ion and HPO4–, which is the conjugate base.
What is the conjugate base of HPO42 -?
The conjugate base of HPO42− is PO43−. Thus option A is the correct answer to this problem. Some acids are capable of donating multiple protons hence the conjugate base of an acid can be acidic itself.
Is HPO42 a strong base?
It is a pretty strong weak base, but it is still a weak base.
What is HPO4 called?
The compound ion HPO4 is called hydrogen phosphate. Common chemical compounds that contain hydrogen phosphate include ammonium hydrogen phosphate, potassium hydrogen phosphate, sodium hydrogen phosphate, lithium hydrogen phosphate, tin(IV) hydrogen phosphate and iron(II) hydrogen phosphate.
Is CH3COO an acid or base?
CH3COOH is a weak acid and dissociates partially in solution (as indicated with reversible arrow) to form H+ and CH3COO- ions. Since this is a reversible process, CH3COO- can accept H+ to form back CH3COOH. Therefore the nature of CH3COO- is basic and we call CH3COO- the conjugate base of CH3COOH.
Is NH4+ an acid or base?
NH4+, aka ammonium ion, is for all practical purposes an acid. It readily “gives off” a proton in the form of h+. NH4+ is the conjugate acid of the base, NH3, aka ammonia.
What is the conjugate base of H3O+?
The HF has given a proton to the H2O, forming H3O+ and F–. Since the product H3O+ can donate a proton back to F– it is labeled the conjugate acid, while the F– is the conjugate base.
What is hso4 conjugate base?
The sulfate ion ( SO4 2− ) is the conjugate base of HSO−4. Reason: Even if it has a negative charge, it will never accept a H+ ion to form H2SO4 again. That is because sulfuric acid is a strong acid and completely disassociates in water. That’s why Sulphate Ion would be the conjugate base formed.
How do you find the conjugate base?
The formula of the conjugate base is the formula of the acid less one hydrogen. The reacting base becomes its conjugate acid. The formula of the conjugate acid is the formula of the base plus one hydrogen ion. Let us illustrate this system using the neutralization of hydrochloric acid with sodium hydroxide.
Is H2PO4 strong or weak?
Salts containing the anion H2PO4 ‾ are weakly acidic. The tendency of this ion to dissociate is greater than its tendency to hydrolyse, that is, its Ka2, is larger than its Kb. Because H2PO4 ‾ is weakly acidic and of low toxicity, it is used as the acid in some baking powders.
Which is stronger H2PO4 or HPO4?
H3PO4 is a weak acid, after the first H+ has left, the next acid H2PO4 ^- is weaker because the left part has a larger minus charge. So the last acid HPO4 ^2- must be the weakest.
Is HNO3 strong or weak?
Strong acids generally have negative pKa’s (i.e. Ka>1), and weak acids generally have positive pKa’s (i.e. Ka<1). Most chemists memorize the most common strong acids HCl, HBr, HCl, HI, HClO4, H2SO4, and HNO3.
Is phosphate same as PH?
They are not the same and don’t really even relate to each other.
What is phosphate used in?
Phosphate rock is processed to produce phosphorous, which is one of the three main nutrients most commonly used in fertilizers (the other two are nitrogen and potassium). Phosphate can also be turned into phosphoric acid, which is used in everything from food and cosmetics to animal feed and electronics.
Is acetic acid a strong acid?
Explanation: Acetic acid, CH3COOH, is a weak acid, because it is present in solution primarily as whole CH3COOH molecules, and very little as H+ and CH3COO− ions. Which furthermore indicates that acetic acid is weak, because strong ions ionize almost completely.
