The procedure to use the pH calculator is as follows: Step 1: Enter the chemical solution name and its concentration value in the respective input field. Step 2: Now click the button "Calculate" to get the pH value. Step 3: Finally, the pH value will be displayed in the new window. We can use the rearranged molarity equation to calculate the moles of NaCl needed for the specified concentration and volume: mol NaCl = [ NaCl] × L of solution = 0.800 mol L × 0.250 L = 0.200 mol NaCl. We can then use the molecular weight of sodium chloride, 58.44 g mol , to convert from moles to grams of NaCl : Question: Calculate the pH of an aqueous solution of HNO3 at the concentration of 0.5M. Its pH should be about 0.3 (and pH value has no unit). The questions you need to consider before performing this calculation are: i. How would I obtain the concentration of H∗,[H+], for use in the formula, pH=−log[H∗] ? See ii. ii. H+(aq) + OH−(aq) ⇋ H2O(l) H ( a q) + + O H ( a q) − ⇋ H 2 O ( l) When a strong acid and a strong base fully neutralize, the pH is neutral. Neutral pH means that the pH is equal to 7.00 at 25 ºC. At this point of neutralization, there are equal amounts of OH− O H − and H3O+ H 3 O +. There is no excess NaOH N a O H. pH + pOH = 14 (Eq. 3) This relationship can be used to convert between pH and pOH . In combination with Eq. 1a/b and Eq. 2a/b, we can always relate pOH and/or pH to [ OH −] and [ H +] . For a derivation of this equation, check out the article on the autoionization of water. For a 0.11 M solution of HNO3, calculate: [H+], pH, pOH, and [OH-] Determine all pH and pOH values to two decimal places. 0.50 L of a HNO_3 solution has a pH of 3.30. Calculate the number of moles of HNO_3 in the solution. HNO3 is a strong acid. Calculate the pH of an aqueous 0.69 M solution. What is the pH of a 0.0001 M solution of HNO3? pOH? Chemistry Solutions Solutions. 1 Answer anor277 May 30, 2016 #pH=-log_(10)H_3O^+#; in water #pOH=14-pH# Explanation: #log_10 Calculate the amount of 1 M NaOH aqueous solution needed to make 100 mL of 0.5 M NaOH aqueous solution. Strong acids are H3O plus, HNO3, H2SO4, HCl, and HBr. Negligible acids are HS minus and OH minus. Stron bases are O negative 2, S negative 2. Negligible bases are NO3 minus, HSO4 minus, Cl minus, and Br minus. The relative strengths of some common acids and their conjugate bases are shown graphically in Figure \(\PageIndex{1}\).
