Is NaOH H2SO4 Na2SO4 H2O balanced?
Is NaOH H2SO4 Na2SO4 H2O balanced?
NaOH + H2SO4 gives Na2SO4 + H2O. Answer: The equation in which the number of atoms of all the molecules is equal on both sides of the equation is known as a balanced chemical equation. …
What is the net ionic equation of H2SO4 and NaOH?
I’m assuming that you’re talking about the last reaction—H2SO4 (aq) + 2 NaOH (aq) → Na2SO4 (aq) + 2 H2O (ℓ). When we break this up into its ions, we get H2 (aq) + SO4(2−) (aq) + 2 Na+ (aq) + 2 OH− (aq) → 2 Na+ = SO4(2−) (aq) + 2 H2O(ℓ). So we can “cancel” the 2 Na+ (aq) and the SO4(2−) (aq) on each side.
What is the net ionic equation for the reaction of H2SO3 with NaOH?
H2SO3 + NaOH = Na2SO3 + H2O – Chemical Equation Balancer.
What is the net ionic equation for HCl and NaOH?
HCl +NaOH = NaCl + H20.
Which acid is the strongest?
perchloric acid
Is NaOH a strong acid?
As it turns out, there are very few strong acids, which are given in Table 12.2 “Strong Acids and Bases”. If an acid is not listed here, it is a weak acid. It may be 1% ionized or 99% ionized, but it is still classified as a weak acid….Learning Objectives.
| Acids | Bases |
|---|---|
| HCl | LiOH |
| HBr | NaOH |
| HI | KOH |
| HNO 3 | RbOH |
What’s the worst acid?
The 4 Most Dangerous Acids in the World
- Aqua Regia. Strong acids typically dissolve metals, but some metals are stable enough to resist the effects of acid.
- Piranha Solution. Piranha solution, or Caro’s acid (H2SO5), is like a voracious chemical version of the carnivorous fish.
- Hydrofluoric Acid.
- Fluoroantimonic Acid.
Is HClO4 stronger than H2SO4?
oxyacids. …it can be predicted that perchloric acid, HClO4, is a stronger acid than sulfuric acid, H2SO4, which should be a stronger acid than phosphoric acid, H3PO4. For a given nonmetal central atom, the acid strength increases as the oxidation number of the central atom increases.
Why is HClO4 the strongest acid?
In Group 17 oxyacids, electron density is drawn away from the O atom as the electronegativity of the halogen increases. This in turn draws electron density away from the O–H bond and weakens it. The weaker the O–H bond, the stronger the acid. Cl is more electronegative than Br so HOClO3 is stronger acid than HOBrO3.
Is HClO4 a strong acid?
The 7 common strong acids are: HCl, HBr, HI, HNO3, HClO3, HClO4 and H2SO4 (1st proton only). They simply do not ionize completely whereas a strong acid or base does.
Is HClO4 stronger than HClO3?
HClO4 is a stronger acid than HClO3 .
Is HClO3 or HClO2 stronger?
The general rule is that the acid is stronger if it has more O atoms in a series such as this. HClO4, perchloric acid, is a very strong acid as is HClO3. HClO2 is a weak acid and HClO is even weaker. HClO3 (chloric acid) is a stronger acid than HClO2 (chlorous acid) for the following reason.
Is HClO3 stronger than HBrO3?
HClO3 is stronger compared to HBrO3. This is because the ClO3- ion is more stable than BrO3- ion because the negative charge on oxygen is reduced by stronger backbonding with Cl atom compared to Br atom because of large difference in energy level of Br and O.
Why is HClO2 a weak acid?
Weak Acid: dissolves but less than 100% dissociates to produce protons (H+) 1. any acid that is not one of the seven strong is a weak acid (e.g. H3PO4, HNO2, H2SO3, HClO, HClO2, HF, H2S, HC2H3O2 etc.) 2. solutions of weak acids have a low concentration of H+.
Is BA OH 2 strong or weak?
Classifying Electrolytes
| Strong Electrolytes | strong acids | HCl, HBr, HI, HNO3, HClO3, HClO4, and H2SO4 |
|---|---|---|
| strong bases | NaOH, KOH, LiOH, Ba(OH)2, and Ca(OH)2 | |
| salts | NaCl, KBr, MgCl2, and many, many more | |
| Weak Electrolytes | ||
| weak acids | HF, HC2H3O2 (acetic acid), H2CO3 (carbonic acid), H3PO4 (phosphoric acid), and many more |
Is HF stronger than HCl?
You are correct, HCl is a stronger acid than HF. Fluorine is both more electronegative and smaller than chlorine. Because fluorine is more electronegative, the bond between it and the hydrogen is more polar, meaning that the proton would need to overcome a larger coulomb force to separate from the fluorine.
What are the 7 strong acids?
There are 7 strong acids: chloric acid, hydrobromic acid, hydrochloric acid, hydroiodic acid, nitric acid, perchloric acid, and sulfuric acid. Being part of the list of strong acids doesn’t give any indication of how dangerous or damaging an acid is though.
What are 3 weak acids?
Some common examples of weak acids are listed below.
- Formic acid (chemical formula: HCOOH)
- Acetic acid (chemical formula: CH3COOH)
- Benzoic acid (chemical formula: C6H5COOH)
- Oxalic acid (chemical formula: C2H2O4)
- Hydrofluoric acid (chemical formula: HF)
- Nitrous acid (chemical formula: HNO2)
How can you tell if an acid or base is strong or weak?
Strong acids and bases are 100% ionized in aqueous solution. Weak acids and bases are less than 100% ionized in aqueous solution. Salts of weak acids or bases can affect the acidity or basicity of their aqueous solutions.
How do you tell if an acid is strong or weak?
Any acid that dissociates 100% into ions is called a strong acid. If it does not dissociate 100%, it is a weak acid.
What is the pH of a 0.010 M solution of HCl?

What is a weak acid Example?
Examples of weak acids include acetic acid (CH3COOH), which is found in vinegar, and oxalic acid (H2C2O4), which is found in some vegetables. VinegarsAll vinegars contain acetic acid, a common weak acid.
Why is HF a weak acid?
Why Hydrofluoric Acid Is a Weak Acid Because the hydroxonium ion is attached to the fluoride ion, it isn’t free to function as an acid, thus limiting the strength of HF in water. The FHF- bifluoride anion is stabilized by a strong hydrogen bond between hydrogen and fluorine.
