Theory A strong acid is completely ionised in aqueous solution. sgt_blocking_layer.style.opacity=0; Acetic acid with a molar concentration of 0.1 M has a pH of 2.87, and 0.0001 M of acetic acid has a pH of 4.3. Cl− is stronger as a base than HCl is as an acid in acetic acid, which doesn't sound right. The pH value for acetic acid depends on its molar concentration in an aqueous solution. } What is the benefit of having FIPS hardware-level encryption on a drive when you can use Veracrypt instead? Making statements based on opinion; back them up with references or personal experience. Acetic acid is called a differentiating solvent for the hydrohalic acids: HI is strongest, HBr less so and HCl is least strong. } Asking for help, clarification, or responding to other answers. So, yes, Cl- is a stronger base than HCl is an acid in acetic acid. transition: all 3s ease; Why is a weak base more able to deprotonate a strong acid than a weak acid? Cl- is poorly solvated by acetic acid compared to Br- and I-, and the protonation of acetic acid is not especially energetic. return false; The pH of a solution of HCl (a strong acid) is lower than the pH of a solution of CH3COOH (a weak acid) having same concentration. blockingdiv.id = 'sgt_blocking_layer'; How does the altered Extra Attack feature of the Bladesinger (Tasha's Cauldron version) interact with Fighter's additional Extra Attacks? thanks for you answer and for the reference. } So I am asking if this value totally wrong or is it actually quite reasonable? This was much higher than I expected. So whereas the middle of the pH scale is thought of as 7, the middle for acetic acid would be 5.

Hydrochloric acid will be dissociated whereas acetic (pK a = 4.74) and lactic acid (pK a = 3.79) will be undissociated at pH 5.5. -moz-transition: all 1s ease-in-out; Sorry for my badly worded question. s = s.replace( /\u2026/g, '...' ); left:0px; { if (window.XMLHttpRequest) opacity:0; So whereas the middle of the pH scale is thought of as 7, the middle for acetic acid would be 5. -Webkit-opacity:0; -moz-transition: all 3s ease; So basically I am asking, is this value totally wrong or is it actually quite reasonable? display: none; Can flint be obtained from gravel that a player placed when it is mined? this.document.body.style.overflow="hidden"; popupdiv.style.WebkitOpacity=1; var apopupdiv= this.document.getElementById(popupdivname); { It produces higher conccentration of hydrogen ions for a given concentration of the acid as compared with a weak acid and hence has lower pH. s = s.replace( /\u00A9/g, '(c)' ); Scalability problem: is the end of Bitcoin near?

I will prepare 0.1M of acetic acid from 100% acetic acid (17.4M) V = 0.1M (1000ml) and add it into sodium acetate until i get pH4.5 View Preparation of 50 mM Sodium acetate buffer?
