Is ch3nh3 an acid or base?
Answer and Explanation: CH3NH2 or methylamine is a weak base, therefore, its conjugate acid CH3NH3+ (methylammonium ion) is formed when it accepts a proton..
What is the pH of 0.5 M acetic acid?
2.52The pH of 0.5 M acetic acid, CH3COOH, is 2.52.
Is the pH scale?
The pH scale measures how acidic or basic a substance is. The pH scale ranges from 0 to 14. A pH of 7 is neutral. A pH less than 7 is acidic.
Is KCl an acid or base?
The ions from KCl derive from a strong acid (HCl) and a strong base (KOH). Therefore, neither ion will affect the acidity of the solution, so KCl is a neutral salt.
Is HClO4 a strong acid?
The 7 common strong acids are: HCl, HBr, HI, HNO3, HClO3, HClO4 and H2SO4 (1st proton only). … They simply do not ionize completely whereas a strong acid or base does.
What is the pH of ch3coo?
8.9Neglecting [H+], the mass balance equations give [CH3COO ] + [CH3COOH] = 0.1 [CH3COOH] = [OH ] + [HCO3 ] Without carbonic acid we get [CH3COOH] = [OH ] and [CH3COO ]=0.1; then[OH ]2 = 0.1×10 9.24 and pH = 8.9.
Is ch3coo a strong acid?
A weak acid (e.g. CH3COOH) is in equilibrium with its ions in water and its conjugate (CH3COO–, a weak base) is also in equilibrium in water.
Is hno3 a base or acid?
HNO3 is a strong acid, sometimes a base, nitrating agent and a strong oxidising agent. It works as a base in the presence of a stronger acid.
Why is acetic acid a stronger acid than water?
The fact that HCl is a stronger acid than the H3O+ ion implies that the Cl- ion is a weaker base than water. … The values of Ka for these acids suggest that acetic acid is a much weaker acid than the H3O+ ion, which explains why acetic acid is a weak acid in water.
Is Hcooh a strong acid?
A strong acid is an acid that completely dissociates in aqueous solution. A weak acid is an acid that partially dissociates in aqueous solution. Figure 1 Formic acid (methanoic acid, HCOOH) is a weak acid that occurs naturally in bee and ant stings. … The acid was once prepared by distilling ants!
Why is ch3cooh a weak acid?
CH3COOH is weak acid because it doesn’t completely dissociate into CH3COO- and H+ ions in water also two oxygen atoms resonate with each other and it forms a strong conjugate base with the O- ion easily able to conjugate with its counterpart being negatively charged.
Is methylamine a base or acid?
Methylamine is a Bronsted base, as it can accept a proton from water.
Is HCN a base or acid?
Hydrogen cyanide is weakly acidic with a pKa of 9.2. It partially ionizes in water solution to give the cyanide anion, CN−. A solution of hydrogen cyanide in water, represented as HCN, is called hydrocyanic acid. The salts of the cyanide anion are known as cyanides.
Is NaHSO4 an acid or base?
NaHSO4 is a very weak acid, in water it will dissociate into Na+ and HSO4- ions and HSO4- can give off some protons since it acts as a weak acid. Na2SO4 is actually a very weak base since it can accept protons SO42-+H+ –> HSO4-.
