What else can I help you with?
Is it possible to have a concentrated solution of a weak acid or base True or False?
True. It is possible to have a concentrated solution of a weak acid or base, as the concentration of a solution refers to the amount of solute dissolved in a solvent, regardless of the strength of the acid or base. The degree of dissociation may be low, but the concentration can still be high.
What is a true Arrhenius acid?
it produces hydrogen ion
What is true about buffer solutions?
They maintain a relatively constant pH when acids or bases are added. Buffers are substances that minimize changes in the concentrations of H+ and OH- in a solution. Buffers do so by accepting hydrogen ions from the solution when they are in excess and donating hydrogen ions to the solution when they have been depleted.
Which one of the following produces hydrogen ions in a water solution?
Acids are dissociated forming hydrogen cations.
True or false an acid- base mixture is always more acidic than the starting solution were?
False. An acid-base mixture may be more, less, or equally acidic compared to the starting solutions depending on the specific pH of the components and their concentrations. The final acidity of the mixture is determined by factors such as their strengths, amounts, and their chemical interactions.
What is the difference between a concentration and a dilute?
A concentrated acid has more acid than water and a dilute acid has more water than acid. True facts, otherwise known as its molarity. The greater the molarity the more concentrated it is (moles of acid/ liter of solution)

What is known as a buffer in science?
A Buffer Is a Solution Containing a weak Acid and its conjugate base Ex. HC2H3O2 acetic acid and its conjugate base the acetate Ion C2H3O2 with a minus 1 charge. Buffer solutions resist changes to pH Because as acid is added the conjugate base in the solution reacts with the acid to neutralize it. The same is true for weak bases and and their conjugate acid.
Is a neutral solution a acid or a base?
A neutral solution is true neutral with a pH of 7,00.
Is starch added to water at room temperature a true solution?
No, starch added to water at room temperature forms a colloidal suspension, not a true solution. The starch particles do not fully dissolve in the water but dispersed throughout, leading to a cloudy mixture rather than a clear solution.

What is the difference between a dilute solution of nitric acid and a concentrated one?
The difference is gradual, but not sharply drawn:Diluted means (more) lower concentration, in laboratory practice less than 1.0 M (
Is it true that a strong acid produces more hydronium ions that a weak acid?
Not really, in the sense that that's not a part of the definition. In practice, it may be the case, but the real definition is that strong acids fully dissociate in dilute solution and weak acids don't.
What is always true about a weak acid?
A weak acid partially dissociates in solution, meaning it does not fully ionize. This results in a low concentration of H+ ions in solution compared to a strong acid. Weak acids have a higher pH and a lower tendency to donate protons than strong acids.
