How do acids and bases differ?
Acids release hydrogen ions in water, lowering the pH below 7. Bases accept hydrogen ions or release hydroxide ions in water, raising the pH above 7. Acids can be corrosive and sour-tasting, while bases can be slippery and bitter-tasting.
Do bases turn phenolphthalein clear?
No, bases turn phenolphthalein pink or purple in color. Phenolphthalein is colorless in acidic solutions and turns pink in basic solutions with a pH higher than around 8.2.
Could any of the properties of acids and bases be conductors of electricity?
Yes, acids and bases that ionize in water can conduct electricity. When dissolved in water, acids release hydrogen ions (H+) and bases release hydroxide ions (OH-), which allow for the flow of electric current. Strong acids and bases are better conductors than weak ones.
What is the difference between a strong acid or base and a weak acid or base?
Strong acids/bases will dissociate to almost 100% in water and their conjugate base/acid will be weak. Weak acid/base will not dissociate well in water and their conjugate base/acid will be strong.
How can compounds be classified by their pH?
Compounds can be classified by their pH into three main categories: acids, bases, and neutral substances. Acids have a pH less than 7, indicating a higher concentration of hydrogen ions (H⁺), while bases have a pH greater than 7, reflecting a higher concentration of hydroxide ions (OH⁻). Neutral substances, such as pure water, have a pH of around 7. This classification helps in understanding the chemical behavior and reactivity of different compounds in various environments.
Does a base have a pH of greater or less than 7?
no acids are higher than seven and bases are lower than seven
Is acids and bases corrosives?
Yes, concentrated acids and bases are more corrosive than dilute acids and bases
What has more OH- ions acids or bases?
Bases have more OH- ions than acids. Acids typically contain more H+ ions, while bases contain more OH- ions. The pH scale represents the concentration of H+ ions, with acids having a pH lower than 7 and bases having a pH higher than 7.
How do acids differ from basis?
Acids have a pH level below 7 while bases have a pH above 7. The chemical difference between acids and bases in the hydrogen ion concentration[H+]. Acids have a higher concentration of hydrogen ions while bases have a higher hydroxide ion concentration[OH-]
What is true about bases on the pH scale?
Bases have values higher than 7 Substances with a pH of 7 are neutral Acids have a pH below 7
How can acids be distinguished from from bases?
Acids are with a pH of less than 7, and bases are when something has a pH of more than 7. Basic solutions are such because of the Hydroxide Ion concentration ([OH-]) and acids are such due to the hydrogen ion concentration (Hydronium Ion) which is [H3O+] or you may see it as just [H+].
What is used to store strong acids and bases?
The most economical route while not compromising safety is storage in wooden cabinets. Acids together and Bases in another box together away from the acids. Do not place storage boxes higher than chest high.
What is the pH rangr for acids bases?
The pH range for acids is 0-6.9, with lower numbers indicating stronger acidity. The pH range for bases is 7.1-14, with higher numbers indicating stronger basicity. A pH of 7 is considered neutral.
What distinguishes a strong acid or base from a weak acid or base?
Strong acids or bases completely dissociate in water to produce ions, causing a high concentration of ions in solution. Weak acids or bases only partially dissociate in water, resulting in a lower concentration of ions in solution. Strong acids and bases typically have higher dissociation constants and stronger interactions with water molecules than weak acids and bases.
Do strong acids or bases react more easily with materials than do weak acids and bases?
Strong acids and bases react more easily with materials than weak acids and bases because they completely dissociate into ions, making them more reactive. Weak acids and bases only partially dissociate, limiting their reactivity with materials.
What turns litmus to blue?
Litmus paper turns blue in the presence of a base, as bases have a higher pH than acids. The blue color indicates that the solution is basic.
Strong acids or bases react more easily with materials than do weak acids and bases?
no they act stronger
