Answer: CL3CCOOH is the strong acid because it gets fully ionise in water in such a way that CL3CCOO+H. as we see in above lines that this acid separates its all hydrogen ions and it fully ionise in water.
Then, Can acid destroy a diamond?
No, acids cannot dissolve diamonds, for the simple reason that a diamonds carbon atoms are too tightly packed together for the Hydrogen ions to be able to dissolve the substance.
Which acid is strongest cl3ccooh? Thus, the order of acidity is: CCl3COOH > CHCl2COOH > CH2ClCOOH > CH3COOH. 7. So, the strongest acid is CCl3COOH.
Keeping this in consideration, Which is the strongest acid HCOOH C6H5COOH?
Acetic acid is the strongest, though still a weak acid here.
Which is harder than diamond?
Buckypaper. It is well-known since the late 20th-century that there’s a form of carbon that’s even harder than diamonds: carbon nanotubes. By binding carbon together into a hexagonal shape, it can hold a rigid cylindrical-shaped structure more stably than any other structure known to humankind.
Can water dissolve a diamond?
Diamond is insoluble in water. … Every atom in a diamond is bonded to its neighbours by four strong covalent bonds, leaving no free electrons and no ions .
Which carboxylic acid is the strongest?
Similarly, chloroacetic acid, ClCH2 COOH, in which the strongly electron-withdrawing chlorine replaces a hydrogen atom, is about 100 times stronger as an acid than acetic acid, and nitroacetic acid, NO2CH2 COOH, is even stronger.
Which of the following is strongest acid Mcq?
HI is the strongest acid. The increasing order of the acid strength is HF<HCl<HBr<HI.
Which is the strongest acid pKa given?
∴ Formic acid with lower pKa value of 3. 77 is the strongest acid.
Which is the strongest acid pKa value?
Some common strong acids ( acids with pKa < -1) include:
- Hydroiodic acid (HI): pKa = -9.3.
- Hydrobromic acid (HBr): pKa = -8.7.
- Perchloric acid (HClO 4 ) : pKa ≈ -8.
- Hydrochloric acid (HCl): pKa = -6.3.
- Sulfuric acid (H 2 SO 4 ): pKa1 ≈ -3 (first dissociation only)
- p-Toluenesulfonic acid : pKa = -2.8.
- Nitric acid (HNO 3 ): pKa ≈ -1.4.
Which is the strongest acid pKa?
In addition, the smaller the pKa value, the stronger the acid. For example, the pKa value of lactic acid is about 3.8, so that means lactic acid is a stronger acid than acetic acid.
Can you break a diamond with a hammer?
As an example, you can scratch steel with a diamond, but you can easily shatter a diamond with a hammer. The diamond is hard, the hammer is strong. … This makes the diamond incredibly hard and is why it is able to scratch any other material. Steel, on the other hand, has an ionic structure.
What is the toughest thing in the world?
Diamond is the hardest substance found on earth in so many natural forms, and it is an allotrope of carbon. The hardness of diamond is the highest level of Mohs hardness – grade 10.
What is the strongest rock in the world?
Diamond is the hardest known mineral, Mohs’ 10.
Can vinegar melt diamonds?
Actually vinegar can help you. It is a versatile product that can be used as seasoning and jewelry cleaner. But vinegar cannot be used to clean gemstones, gold or pearl. It can damage gemstones and gold, and dissolve pearls.
What is the hardest substance on earth?
Diamond is the hardest substance found on earth in so many natural forms, and it is an allotrope of carbon. The hardness of diamond is the highest level of Mohs hardness – grade 10. Its microhardness is 10000kg/mm2, which is 1,000 times higher than quartz and 150 times higher than corundum.
Can you melt a diamond?
In the absence of oxygen, diamonds can be heated to much higher temperatures. Above the temperatures listed below, diamond crystals transform into graphite. The ultimate melting point of diamond is about 4,027° Celsius (7,280° Fahrenheit).
Why is COOH more acidic than Oh?
Answer : Carboxylic acids are more acidic than alcohols or phenols, although all of them have a hydrogen atom attached to an oxygen atom (—O—H) because the conjugate base of carboxylic acids or the carboxylate ion is stabilized by resonance.
What is R COOH?
Carboxylic acid (RCOOH; RCO2H): A molecule containing the carboxyl group. Carboxylic acids are so named after the ease in which the carboxyl group gives up a proton (pKa usually in the range of 0-5). General carboxylic acid structure. X = a carbon group or a hydrogen atom. Some Common Carboxylic Acids.
Does Low pKa mean stronger acid?
The pKa essentially tells you how much of the acid will actually dissociate. If the pKa is low, then more of the acid will dissociate, representative of a stronger acid.
Which is strongest acid HCl or hi?
HI has longer bond than HCl, making its bond weaker. Therefore it is easier for HI to lose H+, making it a stronger acid.
Which of the four acid is strongest acid?
Some common strong acids (acids with pKa < -1) include:
- Hydroiodic acid (HI): pKa = -9.3.
- Hydrobromic acid (HBr): pKa = -8.7.
- Perchloric acid (HClO 4 ) : pKa ≈ -8.
- Hydrochloric acid (HCl): pKa = -6.3.
- Sulfuric acid (H 2 SO 4 ): pKa1 ≈ -3 (first dissociation only)
- p-Toluenesulfonic acid: pKa = -2.8.
- Nitric acid (HNO 3 ): pKa ≈ -1.4.
Which is stronger acid HCl or h2so4?
Generally, both Hydrochloric acid (HCl) and Sulfuric acid (H2SO4) are really strong acids compared to any other acids. However, HCl is stronger than H2SO4. This is mainly due to the difference in the basicity of both acids. Additionally, if we look at the pKa value HCl has a pKa of -6.3 and sulfuric acid has a pKa ~-3.
What pKa is considered a weak acid?
Weak acids have large pKa’s (2 — 50); they are stable because they have high affinity for their protons and want to stay bound to them. The pKa of acetic acid is 4.76. Acetic acid is a moderately weak acid; it dissociates partly when dissolved in water.
