-OH negative ions
A neutral solution.
pure water is neutral with a pH of 7
A neutral solution can contain ions of hydrogen, hydroxide, and the cation and anion of any neutral salt. There are equal numbers of hydrogen and hydroxide ions, and also an equal (but usually different) number of the other pair of ions.
neutral
Yes they are. Remember that all atoms have a neutral charge, so that means that the number of negatively charged electrons has to be equal to the positively charged protons.
No. If the number of H+ and OH- ions are equal then the solution is neutral. A solution is considered alkaline if it has more OH- ions than H+ ions.
an equal number of H3O+ ions and OH- ions
Because any solution have equal number of positive and negative ions, thus becomes neutral.
No. pH is the negative logarithm of the concentration of the hydronium ion. Equal numbers of hydronium ions and hydroxyl ions occurrs only when a solution is neutral.
Neutral.
Neutral.
neutral
A solution that contains equal concentrations of hydrogen and hydroxide ions is neutral. Water is the prime example.
Technically it is called water because the positive hydrogen ions and the negative hydroxide ions would attract to form a compound with two hydrogen molecules and one oxygen molecule. H2O. This occurs most often in acid-base neutralization reaction where water is a product of the reactions.
Because the number of positive hydrogen ions produced is equal to the number of negative ions produced, water is neutral. Water is neutral despite the production of hydrogen ions and hydroxide ions because the number of positive hydrogen ions produced is equal to the number of negative ions produced, water is neutral.
A neutral solution has an equal number or concentration of hydrogen and hydroxide ions. A neutral solution is one that has a pH of 7.0. Pure water is a neutral solution.
