A basic solution has greater concentrations of OH- than H+ ions. The opposite is acidic. An easy mnemonic device for this is that you want to get an A+ not a B-.

What does the pH if a solution depend on?
the concentration of OH ions in solutions
What is the ion present in all basic solutions?
the hydrogen ion (H+)
Why is milk of magnesia a base?
Milk of magnesia is a solution of magnesium hydroxide (a white powder) in water. It is a base because when the powder is introduced into water, it partially dissociates (breaks up) into magnesium (Mg2+) and hydroxide (OH-) ions. Pure water contains an equal number of OH- ions and another ion called hydronium ions (H3O+). Because the milk of magnesia adds OH- ions to the water, there are now more OH- ions than H3O+ ions. This means you have a base. On the opposite end, if there are more H3O+ ions than OH- ions, which happens when you add vinegar or lemon juice to water, you have an acid. Hope that makes sense!
Do basic solution have h plus ions?
nah man. them acids has them lot. the H+ ions that is. but these basic solutions donate a massif amount of OH- ions compared to H+ ions when added to an aqueous solution.
Which molecule represents an ion found in a glass of water?
OH- and H+
What two solutions have more OH- ions than H ions?
stupiud
Do base solutions have more Hydrogen ions or Hydroxide ions?
No, LESS H+ than OH- ions in basic water solutions.
What are solutions that have an equal concentration of H plus ions and OH ions considered as?
Neutral solutions.
What either accept H plus ions from solutions or donates OH- ions to solutions?
This is the definition of a base.
What two solutions have more H plus ions than OH- ions?
An arrhenius acid is, by definition, a solution with a higher concentration of H+ ion than OH-.
Bases are solutions which contain an excess of?
OH- Ions
What do aqueous solutions of acids contain?
These solutions contain the cation H+ and an anion.
How are the concentrations of hydronium ions and hydroxide ions in aqueous solutions related?
The pH of a solution is related directly to its concentrations of hydronium ions(H3O^+) and hydroxide ions(OH-). Acidic solutions have more hydronium ions than hydroxide ions. Neutral solutions have equal numbers of the 2 ions. Basic solutions have more hydroxide ions than hydronium ions.
What does the pH if a solution depend on?
the concentration of OH ions in solutions
What are solutions that have more OH- than H ions?
An arrhenius acid is, by definition, a solution with a higher concentration of H+ ion than OH-. So any arrhenius acid will fit this definition. Two common acids are Lemon juice and vinegar.
What is a solution called that has more OH-ions H plus ions?
When a solution has more hydrogen ions it will be acidic.
Arrhenius defined a base as a substance that produces ions solutions?
OH-..
