Acid
An example of a solute that dissociates to release hydrogen ions and causes a decrease in pH is an acid. Acids release hydrogen ions when dissolved in water, leading to an increase in the concentration of H+ ions in the solution and a decrease in pH. Examples of acids include hydrochloric acid (HCl) and sulfuric acid (H2SO4).
No. Hydrogen is an element.
Water is the solvent in this case, as it is the substance present in the greatest amount and dissolves the solute (hydrogen and oxygen gases) to form a homogeneous mixture.
Solute = hydrogen peroxide, H2O2Solvent = water
The solvent is water and the solute is hydrogen chloride (HCl).
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.

The material most commonly called "hydrogen peroxide", especially by non-chemists, is a solution of the solute hydrogen peroxide in water as the solvent.
The solute in this case would be the hydrogen gas, as it is being dissolved or absorbed into the palladium. Palladium has the ability to absorb large amounts of hydrogen gas through a process known as hydrogen absorption.
In a solution of hydrogen peroxide, the solute is the hydrogen peroxide itself, while the solvent is typically water since hydrogen peroxide is commonly dissolved in water for use.

Solute = hydrogen peroxide, H2O2Solvent = water
The solvent is water and the solute is hydrogen chloride (HCl).
The number of moles of solute will not change. Too, the molarity of the solution decreases.
A solute added to water decreases the freezing point.
Based on the grammar of your question, you have no idea what solubility is. Solubility- the degree to which a substance can dissolve in a solvent(usually water). Hydrogen bonding is an intermolecular force of attraction that decreases relative solubility.
