What does an increase in the concentration of hydrogen ions in a solution cause?

Two things: and increase both in i) the caustic powers resulting from the dissolution of an acid in water: due to the fact that H+ [hydrogen ions] are what makes an acid An Acid; and ii) an increase in the readings on the pH - level of acid/base - Scale.

How does CO2 decrease the pH?
Adding water does not always decrease pH. pH is a measure of the concentration of hydrogen ions, also called hydronium ions. They are inversely related. More hydrogen ions means a lower pH. A base has a pH greater than 7 (neutral) because it has an increased amount of hydroxide ions which causes a lower amount of hydrogen ions. Adding more water to a base solution causes the concentration of the hydroxide ions to become less, thus due to equilibrium, causing the hydrogen ion concentration to increase. This does cause pH to become less ... decrease. But an acid solution does the exact opposite when water is added. It already has a large concentration of hydrogen ions, but as water is added the concentration decreases and this causes pH to increase.
In the reaction 2SO2 plus O2 Reversible 2SO3 which change would cause the greatest increase in the concentration of SO3?
Increase the concentration of SO2
Does isotonic soultion cause a cell to shrink?
No. An isotonic solution would not cause a cell to shrink, because the concentration of water in the solution and inside the cell is the same. A hypertonic solution would cause a cell to shrink.
What kind of solution will dissociate to release hydrogen ions and cause a decrease in pH?
A dissociated acid release hydrogen cations.
What properties do free hydrogen particles cause in acids?
It protonates the solution to become acidic

Does the acid increase the concentration of hydrogen ions in the solution?
The pH increases. There are two ways to think about this. First, adding hydroxide ions is the same as adding a base, and a base will cause the pH of a solution to become more basic, i.e. increase. Second, hydroxide ions will react with hydrogen ions in the solution to neutralize them, decreasing the concentration of hydrogen ions. Since the pH scale is a negative logarithmic scale, a decrease in the concentration of hydrogen ions means an increase in pH.

Increase the concentration of SO2
Does placing plant cells in a hypotonic solution causes the osmotic pressure to increase?
When a plant cell is placed in a hypotonic solution, the osmotic pressure tends to increase as the water in the cells moves to a place elevated in solute concentration. The osmotic pressure is the chief cause of support in numerous plants.
What is the concentration of hydrochloric acid?
Generally this concentration is 36.5 %. However cocentrations up to just over 40% are possible but require special pressure and cool temperature conditions because the vapor pressure of the hydrogen chloride (which is dissolved into water to make hydrochloric acid) is high enough to cause evaporation of the hydrogen chloride out of the solution which then reduces the concentration unless you have the pressure and temperature conditions.
What effect does the concentration of H ions have on the nature of the solution?
pH is -log10[H3O+]; the negative logarithm (with base 10) of the hydronium concentration (hydrogen ions do not float around on their own. Instead they attach to a water molecule and become a hydronium ion).
Which cause the pH of solution to increase?
Adding a base

No. An isotonic solution would not cause a cell to shrink, because the concentration of water in the solution and inside the cell is the same. A hypertonic solution would cause a cell to shrink.
How does hydrogen ion related to pH?
Acidity (pH level) measures the amount of hydrogen in the mixture. pH is the negative log of the hydrogen ion concentration. so if a solution has a hydrogen concentration of 4.3x10-6moles/litre its pH is 5.37 Answer 2 The hydrogen we are talking about is hydogen ions, i.e. what cause acidity. pH stands for 'potential hydrogen'.
What kind of solution will dissociate to release hydrogen ions and cause a decrease in pH?
A dissociated acid release hydrogen cations.
What is the difference between the hypotonic and hypertonic?
A hypertonic solution has more solutes than a cell, where the cell shrinks and possibly dies but a hypotonic solution, meanwhile, has less solutes than a cell where the cell expands and possibly bursts.
What can increase the voltage difference between a metal electrode and a solution?
If electrons are left behind in metal this will increase the voltage difference between a metal electrode and a solution. Also if the solution becomes more positive this will cause an increase.
