To calculate the pH of HCl you need to know the concentration expressed in molarity (mol HCl/L solution). You will use the following equation to find the pH. pH = -log[H+] This means you take the negative log of the hydrogen ion concentration to find the pH. The hydrogen ion concentration is the same as the concentration of the acid because HCl is a strong acid and dissociates as follows: HCl ...


Since the pH scale is logarithmic, not linear, a solution of pH 1 would have ten times (not twice) the [H+] that a solution of pH 2. Likewise, a solution of pH 12 would be 10 times more alkaline than a solution of pH 11. pH Calculations Involving HCl Solutions 1. Given the Wt% of an HCl solution, what is its theoretical pH value? +For pH ...


calculate the pH of the solution resulting from the addition of 50.0 mL of 0.20 M HCl with 30.0 mL 0.15 M NaOH. please work it out step by step.


To calculate the pH you can use the equation: pH= -log[H3O+]. In case of HCl (very strong acid) you can assume that it is 100% ionised in H2O. Therefore, pH= -log (molarity).


Calculating pH. To calculate the pH of an aqueous solution you need to know the concentration of the hydronium ion in moles per liter . The pH is then calculated using the expression: pH = - log [H 3 O +]. Example: Find the pH of a 0.0025 M HCl solution. The HCl is a strong acid and is 100% ionized in water. The hydronium ion concentration is 0 ...


I will assume you know about basic chemistry ,equilibrium and how to do calculations with logarithms and exponentials. What you must first understand is dissosiation and ionic equilibrium. In a solution, AB(aq) can undergo certain dissosiation unt...


Find the pH of a 0.03 M solution of hydrochloric acid, HCl. Remember, Hydrochloric acid is a strong acid that dissociates according to a 1:1 molar ratio into hydrogen cations and chloride anions. So, the concentration of hydrogen ions is exactly the same as the concentration of the acid solution.


To work this out you the relationship pH=-log10[H+] pH=-log10[0.2] pH=0.7 You can then enter this into the equation pH + pOH = 14 placing our pH value into this we get 0.7 + pOH = 14 You can rearrange this to find pOH = 14–0.7 which means pOH=13.3


Example 1: Calculate the pH of a 0.200 M HCl solution. HCl solutions are strong acids, so we can already expect a pH less than 7. Using the 0.200 M HCl as the [H+] (concentration of hydrogen ions) the solution is as follows: pH=-log { left[ { H }^{ + } right] } = log(0.200) =0.70. A 0.70 pH indicates a very acidic solution. Example 2: Calculate ...


pH = 1.63 Concentration of HCl is 0.0235 M [HCl] = 0.0235 mol/ L as HCl is a strong acid, it will completely dissociate and produce H^+ ions. [ H^+] = 0.0235 mol/ L pH = -log [ H^+] pH = - log [0.0235] pH = -(-1.628) pH = 1.63
