What else can I help you with?
What is the ion present in all basic solutions?
The hydroxide ion, OH-, is present in all basic solutions. It is responsible for the characteristic properties of basic solutions, such as a bitter taste, slippery feel, and ability to turn litmus paper blue.
What happens to the hydroxide ion concentration in aqueous solutions when you increase the hydrogen ion concentration by adding an acid?
The hydroxide ion concentration would decrease in response to the increase in hydrogen ion concentration. This is due to the neutralization reaction that occurs between the added acid (which releases H+ ions) and the hydroxide ions (OH-) present in the solution.
What makes an acid or base weak?
H+ion concentration in the solutions
Why does acid show acid not show acidic behaviour in absence of water?
The definition of an acid is the formation of the hydronium ion, H3O+. This comes about ONLY in the presence of water, H2O, where H2O + H+ ==> H3O+. It is a phenomenon of aqueous solutions, so water must be present.
Is chloride a liquid?
No, chloride is an ion and does not exist in isolation. Chlorine is a gas.
what is the molarity of H30?
The molarity of H3O+ (hydronium ion) would depend on the specific solution being referred to, as it is generally formed in acidic solutions. To calculate the molarity of H3O+, you would need to know the concentration of the acid present in the solution and the dissociation constant of the acid.
Is hydrogen sulphate an acid or an alkali?
Hydrogen sulfate (also known as bisulfate) is an acid. It is formed by the partial neutralization of sulfuric acid, which is a strong acid. Hydrogen sulfate ion acts as an acid by donating a hydrogen ion in aqueous solutions.
Why do hydronium ions form in aqueous acid solutions?
Hydronium ion (H3O+) form in aqueous solution because the water molecule, H2O can accept a proton which is donated from an acid. Thus, the proton (H+) reacts with H2O to produce H3O+, the hydronium ion.
When HCl is dissolved in water the only positive ion present in the solution is?
When HCl (a strong acid) dissolves in water, the positive ion that forms is the hydronium ion, H3O+.
What base is present in base?
The base present in bases is typically a hydroxide ion (OH-). This hydroxide ion is responsible for the alkaline properties of bases, as it can accept a proton from an acid to form water.
Which substance yields H aq as the only positive ion in an aqueous solution?
Hydrochloric acid (HCl) yields H⁺ ions in aqueous solutions. This is because HCl dissociates into H⁺ and Cl⁻ ions when dissolved in water, with H⁺ being the only positive ion present.
When an acid is added to water what ion is released?
When an acid is added to water, hydrogen ions (H+) are released. This is what gives acidic solutions their characteristic properties.
