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.
What changes would cause the fusion rate in the Suns core to increase?
Increase in the core temperature and decrease in the core radius.
In the reaction 2SO2 plus O2 Reversible 2SO3 which change would cause the greatest increase in the concentration of SO3?
Increasing the concentration of either SO2 or O2 would drive the reaction towards the formation of more SO3, resulting in an increase in the concentration of SO3. Increasing the temperature, however, would cause the greatest increase in the concentration of SO3 as it favors the forward reaction which produces more SO3.
How does hypersonic solution and hypotonic solution differ in meaning?
A hypersonic solution refers to a solution that has a higher concentration of solute compared to another solution. On the other hand, a hypotonic solution has a lower concentration of solute compared to another solution. Hypertonic solutions will cause water to flow out of a cell, while hypotonic solutions will cause water to flow into a cell.
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.
Why does the pH drop when temperature increases?
When temperature increases, the pH drops because higher temperatures can cause chemical reactions to occur more quickly, leading to an increase in the concentration of hydrogen ions in the solution. This increase in hydrogen ions lowers the pH level of the solution.
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.
How does the addition of an base affect a neutral solution?
When a base is added to a neutral solution, the pH of the solution will increase. This is because the base combines with the hydrogen ions in the solution, reducing their concentration. As a result, the solution becomes more alkaline and the pH value rises above 7.

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 changes would cause the fusion rate in the Suns core to increase?
Increase in the core temperature and decrease in the core radius.
Why does pH increase when diluting a base?
The pH of a solution does not increase when diluting a base. Since the pH depends inversely on the concentration (rather than number of moles) of hydronium ions (H3O+) in solution, dilution would cause the pH to decrease. Another way to think about this problem is with pOH, which can be related to pH by the approximation: 14-pOH=pH Which is valid under normal conditions. pOH is inversely related to the concentration of hydroxide (OH-) ions. If one dilutes the the solution, there would be a smaller concentration of hydroxide ions, meaning a larger pOH. By the equation above, a larger pOH causes a smaller pH. This agrees with the intuitive reasoning that if a solution is getting less basic, it becomes more acidic, and therefore its pH decreases.
What ions cause a low pH?
Hydrogen ions (H+) cause a low pH. When hydrogen ions are present in a solution, the pH decreases, making the solution more acidic.
Which cause the pH of solution to increase?
Adding a base

How could you increase the concentration of a solution after the saturation point is reached?
With few exceptions, if you increase the temperature of the solvent, you will increase the amount of solute that a solution will hold. So, let's say you have a saturated NaCl solution in water at room temperature. Put the beaker on a hot plate and heat it up, and it will be able to dissolve more salt. Cool it back down and it will become supersaturated (and unstable.)
