Difference between concentrated and diluted acids?
The difference is gradual, but not sharply drawn:Diluted means (more) lower concentration, in laboratory practice less than 1.0 M (
What acid are hazardous?
Of the common laboratory acids, the most dangerous to work with is usually concentrated nitric acid because it reacts so strongly with so many chemicals, releasing poisonous gases. It also fumes, can cause explosions, and instantly oxidizes flesh causing severe burns. There is no easy answer to what is the most dangerous acid because some acids are more corrosive, some are poisonous, and some are explosive. The strongest acid is SbF5 in HF. This is rare and the strongest acid one would find in a normal chemistry laboratory is usually hydrochloric acid, hydrobromic acid, hydriodic acid, or perchloric acid. Hydrofluoric acid is an interesting case - it is a weak acid (it does not ionize) and as a result can be absorbed by the skin very quickly. Once absorbed, it damages tissue causing severe pain, chemical imbalances, and almost certain death if more than 50mL are in contact with skin. Other acids are dangerous because of toxic qualities rather than acidic qualities. Hydrocyanic acid is a poison gas that cannot be detected by everyone. Sulfuric acid is a dangerous dehydrating agent. Hydrochloric acid readily releases toxic fumes and can corrode many metals. Picric acid is extremely explosive. Sulphuric acid can also be dangerous if in contact with eyes, skin, mouth or other acids.
What is the pH of ethanoic acid?
Ethanoic acid is vinegar, it can be diluted to be pH 4 or 5, it can also be very concentrated to be 1 or 2. Most ethanoic acids are 4-5 in pH.
Why do you start with the most dilute solution and measure in order of increasing concentration?
You do this in order to minimize error due to imperfect rinsing. If you start with a high concentration and work your way down, you may transfer concentrated solution to the lower concentrated solution.
Which of the hazard symbols would you most likely to find on a concentrated acid?
The hazard symbol you would most likely find on a concentrated acid is the corrosive symbol. This symbol indicates that the acid can cause severe skin burns and eye damage upon contact. It is important to handle concentrated acids with caution and use appropriate protective equipment.

What acids affect copper the most?
You can dissolve copper in concentrated nitric acid.
What is the difference between Concentrated and corrosive acids?
Concentrated acids have a high amount of acid molecules in a solution, while corrosive acids have the ability to cause damage to materials upon contact due to their chemical properties. Corrosive acids can be concentrated, but not all concentrated acids are corrosive.
What is the acids pH?
The pH of acids ranges between 1 to 6. The one with pH 1 is the most concentrated. The pH is a measure of the concentration of H+ ions in a solution.

Which one H2so4 is most dangerous concentration or dilute?
Concentrate Sulfuric Acid is more dangerous as it is a purer substance. Anything which is dilute has been diluted (mixed) with another substance, usually water.
What is most concentrated nuclear electric or chemical?
You mean enormous? If so nuclear is enormous same time so dangerous.
Are all acids dangerous give examples of safe acids and dangerous ones?
Citric acid is not harmful in most cases, you can find it in many fruits e.g. oranges, lemons and limes. stomach acid smells bad also.
What is the most dangerous industrial acid?
All concentrated industrial acids (HCl, H2SO4, HNO3, etc.) are extremely dangerous and can cause extreme injury. But I guess the MOST dangerous would be hydrofluoric acid (HF). The reason is that HF can penetrate the skin and get into your blood, where the F- reacts irreversibly with your plasma calcium to form CaF2 (which is insoluble) This quickly makes you hypocalcemic. This leads to muscle spasms, tetany, and eventually cardiac arrest. I think an HF burn on your body that is as big as your palm print could kill you, or something like that. Other acids can give you pretty serious burns, but aren't as likely to kill you.
What is a concentrated mineral acid?
Mineral acids are non-organic acids. Sulfuric, nitric, hydrochloric, and phosphoric acids are probably the most important commercially, though they're certainly not the only mineral acids. "Concentrated" generally means "the standard purity supplied by manufacturers." This varies quite a bit depending on the exact acid; it can be nearly pure (sulfuric or nitric acids), somewhat less so (phosphoric acid, typically about 70%), or quite a bit less (hydrochloric acid at around 38% or so).
Why do you start with the most dilute solution and measure in order of increasing concentration?
You do this in order to minimize error due to imperfect rinsing. If you start with a high concentration and work your way down, you may transfer concentrated solution to the lower concentrated solution.
