WebAug 1, 2016 · The $\mathrm{pH}$ of a substance can be negative. $10\ \mathrm M$ solution of $\ce{HCl}$ would have a $\mathrm{pH}$ of $-1$. The stronger the acid, the smaller is the value of $\mathrm{pH}$. $\ce{HCl}$ is a strong acid because it ungergoes almost 100 % dissociation. WebThe pH scale is often said to range from 0 to 14, and most solutions do fall within this range, although it’s possible to get a pH below 0 or above 14.

WebNov 29, 2024 · pH means “power of hydrogen” and is a measure of the hydrogen ion concentration. If the concentration of H+ ions is 10−1 , the pH is 1, and the pOH is 13. The H+ concentration is much higher than the OH− concentration, which makes the substance acidic. Can pH be negative? WebThat gives us pH plus 4.75 is equal to 14.00. And solving for the pH, we get that the pH is equal to 9.25. So we have the pH and our goal is to solve for the concentration of hydronium ions, and pH is equal to the negative log of the concentration of hydronium ions. So we can plug our pH right into this equation.

WebMay 2, 2024 · The equilibrium equation yields the following formula for pH: pH = -log 10 [H +] [H +] = 10 -pH.
