What else can I help you with?
Is BF3-NH3 a salt?
Yes - it is a "Lewis salt" formed from a Lewis acid and a Lewis base. Most chemists would not call it a salt which is a term they would reserve for the product of the neutralisation of an H+ acid. They would call this an adduct or a complex.
What is a substance that produces H plus ions in a water solution?
An acid is a substance that produces H+ ions in a water solution. Examples include hydrochloric acid (HCl) and sulfuric acid (H2SO4).
The strength of an acid based on concentration of what ions?
Hydrogen ion (H+) [technically it is hydronium ion (H3O+)] that determines the strength of an acid. A mole of hydrochloric acid (HCl) produces 1 mole of H+ ions, then that is a strong acid. Weak acids give smaller amounts of H+ for a mole of substance.
What is Ka for H2CO3(aq)H plus (aq) plus HCO3-(aq))?
The acid dissociation constant (Ka) for carbonic acid (H₂CO₃) dissociating into hydrogen ions (H⁺) and bicarbonate ions (HCO₃⁻) is a measure of the strength of the acid in solution. The dissociation reaction can be represented as: H₂CO₃ (aq) ⇌ H⁺ (aq) + HCO₃⁻ (aq). The value of Ka for this process is approximately 4.3 x 10⁻⁷ at 25°C, indicating that H₂CO₃ is a weak acid.
What is the acid dissociation constant for an acid at equilibrium HX H plus plus H-?
The acid dissociation constant (Ka) for the acid dissociation reaction ( \text{HX} \rightleftharpoons \text{H}^+ + \text{X}^- ) is defined as ( K_a = \frac{[\text{H}^+][\text{X}^-]}{[\text{HX}]} ) at equilibrium. Here, ([\text{H}^+]) and ([\text{X}^-]) are the concentrations of the hydrogen ions and the conjugate base, respectively, while ([\text{HX}]) is the concentration of the undissociated acid. A higher ( K_a ) value indicates a stronger acid, as it reflects a greater degree of dissociation in solution.
Why does the H plus ion act as a Lewis acid?
The H+ ion acts as a Lewis acid because it can accept a pair of electrons from a Lewis base to form a coordinate covalent bond. Due to its electron deficiency, the H+ ion is capable of accepting an electron pair, making it a strong electrophile and thus a Lewis acid.
Is HCl a lewis acid?
Yes, HCl can act as a Lewis acid because it can accept a pair of electrons from a Lewis base. In this case, the chlorine atom in HCl acts as the electron acceptor.
Which of the following is an example of a Lewis base out of H3O NH3 BF3 H plus?
NH3 is an example of a Lewis base as it can donate a pair of electrons to form a bond with a Lewis acid. Lewis bases are electron pair donors, while Lewis acids are electron pair acceptors.
Which ion is donated by an acid when added to water OH- OH plus H- or H plus?
H+ or a proton.
What provides H plus?
acid in solution.
How do you distinguish an acid from an alkali?
an acid donates the h plus ion and alkali does the opposite
What is the name of The compound H plus?
Carbonic acid(H2CO3/H(CO3)2
What is the name of a compound that gives off H plus?
Acid
What is Bronsted-Lowry acid and base for HPO4 2- plus H plus?
Hpo2- +f-

What is the acid dissociation constant for an acid at equilibrium HX ----- H (spuare Plus) plus x -?
The acid dissociation constant, Ka, is a measure of how well an acid donates a proton in a chemical reaction. For the reaction HX ⇌ H+ + X-, the expression for Ka is [H+][X-]/[HX]. The value of Ka indicates the strength of the acid - higher Ka values indicate stronger acids.
Any compound that produces H plus ions is what?
An Arrhenius acid
