3.00 g of potassium hydroxide (KOH) pellets are put into a constant-pressure calorimeter containing 250 mL of water. The initial temperature of the water is 22.3°C. The mixture is then stirred until all of the KOH is dissolved. The final temperature of the solution is measured and recorded as 29.7°C. Calculate the heat of solution for potassium hydroxide (ΔHsoln). The specific heat capacity of the solution may be assumed to be the same as that of water since this is...

1.Calculate the [H3O+] value of each aqueous solution. aspirin with [OH−]=1.4×10−11M. seawater with [OH−]=1.5×10−6M 2. To calculate pH and use it as a measure of acidity. What is the pH of an aqueous solution with [H3O+] = 4×10−13M ? Carbonated cola is more acidic than coffee or even orange juice because cola contains phosphoric acid. What is the molar concentration of H3O+ in a cola that has a pH of 3.120?
