a strong acid like HF, H2SO4...are stronger when they are concentrated, weaker acids are weak even they are concentrated
Not necessarily. The concentration of a strong acid in water depends on the amount of acid dissolved in the water. A solution is concentrated if there is a relatively large amount of solute (acid) dissolved in the solvent (water), and dilute if there is a relatively small amount.
Yes, 5M HCl is considered a concentrated strong acid. Hydrochloric acid is a strong acid that fully dissociates in water to produce hydrogen ions. The high concentration of 5M indicates a large number of hydrogen ions available in the solution.
Concentrated acid means there's a lot of it; that is, a high concentration. By convention, "concentrated" means "straight out of the stock bottle," for some acids this is nearly pure and for others it's not (phosphoric acid is typically supplied as a solution that's about 70% w/w phosphoric acid, for example). Lab bottles labeled "dilute" usually contain a 6M solution unless otherwise specified. Strong acid means that it fully dissociates in water (at least the first proton, for multiprotic acids). Strong/weak and concentrated/dilute are completely different scales that have nothing to do with each other. * 18.3M sulfuric acid is strong and concentrated * 6M sulfuric acid is strong and dilute * Glacial acetic acid is weak and concentrated * 6M acetic acid is weak and dilute
An acid is a substance that breaks into water to produce hydrogen ions (H+) and some other, negative ion. A strong acid is and acid that completely breaks apart into ions. (In a weak acid, only some of it breaks apart). Nitric acid is a strong acid while acetic acid is weak. A concentrated acid is one that is nearly pure. Usually 90% pure or more. So 95% nitric acid is a concentrated strong acid, while 95% acetic acid is a concentrated weak acid. Acids are usually sold dissolved in water in a low concentration. For example, vinegar is 5% acetic acid. Hydrochloric acid, another strong acid, is often sold in a 37% concentration.
Drinking squash, concentrated vegetable boullion (stock), some fruit juices are concentrated then diluted again... basically anything that has been boiled to remove the water content is "concentrated".
Concentrated HCl acid is a very strong acid. Note the word 'concentrated'. What does it mean? Concentrated really means that the amount of hydrogen ions in it is very high. The strength of an acid depends upon the amount of hydrogen ions present. If the ions are more, then it is a concentrated acid and if the hydrogen ions are less, then it is a weak acid. As it is strong, handle it cautiously or may cause burns. I believe this satisfies your question.
To prepare a dilute acid solution from a concentrated acid, you can slowly add the concentrated acid to water while stirring. Never add water to concentrated acid as it can cause splattering. Always add acid to water to ensure proper mixing and to prevent violent reactions. Mix well after adding the acid to ensure uniform dilution.
No it is not. Strength refers to the degree to which and acid dissociates in water by releasing its hydrogen, the more it dissociates, the stronger it is. A strong acid dissociates completely. Concentration refers to the number of molecules in a particular volume.
strong acids and bases dissociate completely; weak acids and bases dissociate only partially. In contrast, the term dilute and concentrated are used to indicate the consentration of a solution, which is the amount of acid or base dissolved in the solution. It is possible to have dilute solutions of strong acids and bases and concentrated solutions of weak acids and bases.
It is an Acid, and when concentrated, around 97%, as in batteries, has a pH under 1, (very strong) which can vary depening on the solution.As the name tells, it is an acid
No, the terms "strong" and "concentrated" are not always synonymous. "Strong" typically refers to the intensity or potency of a substance, while "concentrated" usually means that a substance has a high ratio of solute to solvent. In some contexts, a substance can be strong but not concentrated, or vice versa.
Concentration deals with how much you have dissolved in the solution you are using, eg you could have concentrated sulphuric acid 5 moldm-3 or dilute 0.5 moldm-3. Strength in chemistry means how much it will dissociate. So H2SO4 is a strong acid and completely dissociates, so one mole of acid will release two moles of H+. Ethanoic acid is a weak acid and would only release a small number of protons. Acid strength is shown in numbers called the dissociation constant Ka which you can look up in data tables.
