What is an acid an alkali and neutral?
An acid is a substance that donates hydrogen ions in a solution, resulting in a low pH (below 7). An alkali is a base that accepts hydrogen ions in a solution, leading to a high pH (above 7). Neutral substances have an equal balance of hydrogen and hydroxide ions, resulting in a pH of 7.
Is nh3 and nh4cl a buffer?
this is buffer system consisted of a weak base and its conjugated base. NH4OH is the weak acid and the NH4Cl is the conjugated base. when an acid or a base is added in small amount the change of the pH of this solution is neglegible hence we tells that this shows a resistivity when adding an acid or a base .when an acid is added OH ions reacts and form H2O and NH4OH dissociates and give the OH ions to the solution .When an base is added NH+ ions react with OH ions added and form NH4OH which dissociates weakly to NH+ ions and OH- ions .
What does a buffer act like when the pH starts to drop?
When the pH starts to drop, a buffer will resist the change by absorbing excess H+ ions or releasing OH- ions to help maintain a relatively stable pH level. The buffer's ability to neutralize the added acid prevent drastic shifts in pH.
Does an acidic solution contain hydroxide ions?
No, an acidic solution does not contain hydroxide ions. Acids donate protons (H+) in solution, while hydroxide ions (OH-) are found in basic solutions.
How are H plus and OH-ions related acids and bases?
H+ ions are associated with acids as they can donate a proton, making a solution acidic. OH- ions are related to bases as they can accept a proton, making a solution basic. In water, the presence of H+ ions and OH- ions determine the pH level of a solution, with a balance between the two indicating neutrality.
When a base is added to a buffer solution the buffer will?
donate H+ ions
What is and acid?
Acid: A substance that can donate H+ ions. Alkali: A substance that can donate OH- ions.
What is acid and allkaline?
Acid: A substance that can donate H+ ions. Alkali: A substance that can donate OH- ions.
What is the buffer capacity of a solution of a strong base directly proportional to?
The buffer capacity of a strong base is directly proportional to the concentration of hydroyxl ions. Buffer capacity = 2.303 x [OH-]

Write the complete ionic equation for the reaction that occurs when a few drops of potassium hydroxide solution are added to the buffer?
The complete ionic equation for the reaction between potassium hydroxide solution (KOH) and a buffer would involve the dissociation of KOH into potassium ions (K+) and hydroxide ions (OH-), and the respective ions present in the buffer solution. The specific ions present in the buffer would depend on its composition.

How does soil act as a buffer?
acidity is measured in the presence of (H+) ions, whereas a base is measured in the presence of (OH) ions. soil has more (OH) ions so when an acid (such as acid rain) sifts through it, the raid becomes more neutral due to the (OH) ions canceling out the mass amounts of (H+) ions
Does an acidic solution contain hydroxide ions?
No, an acidic solution does not contain hydroxide ions. Acids donate protons (H+) in solution, while hydroxide ions (OH-) are found in basic solutions.
How are H plus and OH-ions related acids and bases?
H+ ions are associated with acids as they can donate a proton, making a solution acidic. OH- ions are related to bases as they can accept a proton, making a solution basic. In water, the presence of H+ ions and OH- ions determine the pH level of a solution, with a balance between the two indicating neutrality.
What is acid what is base?
Acids are substances that donate protons (H+) in a solution, lowering the pH. Bases are substances that accept protons or donate hydroxide ions (OH-), increasing the pH. Acids and bases are usually defined by their behavior in aqueous solutions.
