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 causes volume contraction between ethanol and water?
Hydrogen bonds are formed between water and ethanol molecules, the solution become more "packed"; the density increase and the volume decrease.
What does Calcitonin causes?
a decrease in the blood concentration of calcium
Why a pinch of manganese dioxide causes hydrogen peroxide to explode?
Manganese dioxide is a catalyst for the decomposition of hydrogen peroxide.
What causes decrease in salivary secretion?
Salivary glands secrets saliva in our mouth
what is a solute that dissociates to release hydrogen ions and causes a decrease in pH?
An example of a solute that dissociates to release hydrogen ions and causes a decrease in pH is hydrochloric acid (HCl). When dissolved in water, HCl dissociates into H⁺ and Cl⁻ ions, with the hydrogen ions contributing to the acidity of the solution by increasing the concentration of H⁺ ions, thus decreasing the pH.
What causes HCl to become an acid?
HCl becomes an acid when it dissociates in water to produce hydrogen ions (H+) and chloride ions (Cl-). The presence of hydrogen ions in solution gives HCl its acidic properties, such as the ability to donate protons and lower the pH of a solution.
Does hydrogen chloride have polar or nonpolar bonds?
Hydrogen chloride has polar bonds. The difference in electronegativity between hydrogen and chlorine causes the chlorine end to be slightly negative and the hydrogen end to be slightly positive, resulting in a dipole moment.
How does clonidine act as a sedative?
Clonidine is an alpha-2 adenergic agonist. This means that it stimulates the alpha-2 receptor. This causes a decreased release of norepinephrine and epinephrine. This decrease causes a decrease sympathetic tone acting like a sedative.
What hormone causes the blood sugar level to decrease?
Insulin is the hormone that causes the blood sugar level to decrease.

no

What type of reaction causes stars to combine hydrogen and release massive amounts of radiation?
This involves "nuclear fusion" reactions.
when potassium is added to water what causes explosion?
When potassium is added to water, it reacts exothermically with the water to produce potassium hydroxide and hydrogen gas. The rapid production of hydrogen gas in the reaction causes an explosion due to the build-up of pressure from the gas release.
