What is true of a Arrhenius base?
An Arrhenius base is a substance that dissociates in water to produce hydroxide ions. It increases the concentration of hydroxide ions in the solution, leading to a rise in pH. Arrhenius bases have a pH greater than 7.
What is an acid according to Arrhenius?
When an Arrhenius acid is added to water it increases the number of H+ ions present. a substance that ionizes to yield protons in aqueous solution ~IHATEe2020~
An inorganic base dissociates in water into?
An inorganic base dissociates in water to release hydroxide (OH-) ions. This process increases the concentration of hydroxide ions in the solution, leading to an alkaline pH.
Does the viscosity of water vary with temperature?
Yes, the viscosity of water does vary with temperature. As the temperature of water increases, its viscosity decreases, making it less resistant to flow. Conversely, as the temperature decreases, the viscosity of water increases, making it more resistant to flow.
What makes a substance a strong electrolyte?
A substance is considered a strong electrolyte if it completely dissociates into ions when dissolved in water, allowing for a high conductivity of electric current.
What is a substance that lowers H and decreases pH when it dissociates in water?
A substance that lowers hydrogen ion concentration (H⁺) and decreases pH when it dissociates in water is an acid. When an acid, such as hydrochloric acid (HCl), dissociates in water, it releases H⁺ ions, increasing the acidity of the solution and resulting in a lower pH. This process is fundamental to understanding acid-base chemistry.
How does density of a substance change with temperature and name a substance that does not strictly follow this rule.?
In general, as the temperature of a substance increases, it's density decreases. One exception of this is water. as liquid water approaches it's freezing point, the water molecules rearrange themselves into a lattice structure, actually making it less dense. This is why ice floats on top of water.
The density of sea water increases as?
the density of sea water increases as salinity increases and temperature decreases
What is acidity of substances?
Acid is a substance that, when added to water, dissociates (dissolves) to release H+ ions into the water. The higher percent of the acid that dissociates, the stronger the acid.
Why does speed of light increase after passing through water?
The speed of light depends on the electrical properties of whatever substance it's in. It has nothing to do with what substance it used to be in before, or what substance it's going into next. -- If it goes from air into vacuum, its speed increases. -- If it goes from air into water, its speed decreases. -- If it goes from water into air, its speed increases. -- If it goes from water into diamond or jello, its speed decreases.
In general the density of sea water increases as?
salinity increases and temperature decreases....
Why does density of water below 0 degree Celsius first decreases then increases?
First decreases then increases ... as what changes, exactly? The point of maximum density for liquid water occurs at 3.98 degrees Celsius. This is mainly due to some semi-complicated effects from hydrogen bonding, which is stronger in water than in nearly any other substance.
What decreases as water pressure increases?
Water pressure increases as the water gets warmer. If water is cold, it doesn't provide much pressure because the molecules move slowly.

The density of water is decrease or increase?
yes it decreases in the water
