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.
What else can I help you with?
What type of a liquid has a pH of 1?
pH scale is based on 0-14 scale. 0-6 is acidic with 0 being strong acid, 7 is neutral and 8-14 is basic. Concentrated sulfuric acid has pH of one.
Why does the amino acid phenylalanine give a yellow color with concentrated nitric acid?
Phenylalanine gives a yellow color with concentrated nitric acid due to the formation of nitrophenylalanine derivatives. The concentrated nitric acid nitrates the phenylalanine, leading to the production of nitro groups that impart a yellow hue to the solution. This reaction is part of a broader class of chemical reactions involving amino acids and nitrous compounds, highlighting the interaction between amino acid side chains and strong acids.
How can you use metal oxides to distinguish strong acid from weak acid?
Metal oxides can be used to distinguish strong acids from weak acids based on their reactivity. Strong acids, like hydrochloric acid, will react vigorously with metal oxides, leading to the formation of metal salts and releasing hydrogen gas. In contrast, weak acids, such as acetic acid, do not react significantly with metal oxides due to their lower dissociation in solution. Thus, observing the intensity of the reaction can help identify whether an acid is strong or weak.
What are some examples of concentrated solutions?
Examples: - concentrated solution of sulfuric acid - concentrated solution of nitric acid - concentrated solution of ethanol - concentrated solution of sugar (syrup) - concentrated solution of table salt
What is the difference between the reactions of concentrated hydrochloric acid and dilute hydrochloric acid with magnesium?
Concentrated hydrochloric acid is more reactive than dilute hydrochloric acid. When concentrated hydrochloric acid reacts with magnesium, it produces magnesium chloride and hydrogen gas more quickly and vigorously compared to when dilute hydrochloric acid reacts with magnesium. This is due to the higher concentration of hydrogen ions in concentrated hydrochloric acid, leading to a faster and more intense reaction.
Is a concentrated acid always a strong acid?
a strong acid like HF, H2SO4...are stronger when they are concentrated, weaker acids are weak even they are concentrated
What is the difference between a concentrated acid and strong acid?
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
Difference between strong acid and concentrated acid?
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.
Distinguish between dilute acid or base and concentrated acid or base?
Concentrated acid or base has a high amount of acid or base in a solution, usually at or near 100% concentration. Dilute acid or base has a low amount of acid or base in a solution, usually with a lower concentration. Dilute solutions are weaker and less corrosive, while concentrated solutions are stronger and more reactive.
Is 5m HCl a concentrated weak acid?
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.
How does the difference between a concentrated acid and a diluted acid affects the hazards of the solution?
A concentrated acid is more dangerous.
What is an example of a concentrated solution?
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".
Is Concentrated hydrochloric Acid a weekly or a strongly Acid?
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.
Is a water solution of a strong acid always 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.
What is the difference between dilutes and concentrated acid's?
diluted acid is less concentrated i.e. it is mixed with water and a less harmful(like sulphuric acid.) whereas concentrated acid is in its original form...
In a strong acid the same thing as a concentrated acid?
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.
Can a pH meter be used to distinguish between a strong acid and a weak acid?
Yes, the Ph scale determines an acid/base's concentration. 0-7 on the scale refers to an Acid, and 7-14 Basic. 7=Neutral, neutral being the weakest. The closer to 7 the weaker the acid would be.
