WebYou may assume the temperature is 25 oC. arrow_forward. a) Enough of a monoprotic acid is dissolved in water to produce a 1.291.29 M solution. The pH of the resulting solution is 2.832.83. Calculate the Ka for the acid. b) i) Determine the [OH−] , pH, and pOH of a solution with a [H+] of 8.6×10−10 M at 25 °C. WebA solution whose pH is less than 7 is said to be acidic, whereas a solution whose pH is greater than 7 is said to be basic or alkaline. Chemicals that cause the number of H + ions in water to increase are acids; chemicals that cause the number of OH - ions to increase are bases. As we shall see, [H +] and [OH -] in water are intimately related ...
WebMethod 1. Use properties of the log scale. Recall that \text {pH} pH scale is a negative logarithmic scale. Therefore, if the concentration of \text {H}^+ H+ decreases by a single … WebMay 24, 2015 · 373. May 23, 2015. #2. This is an important trick that must be remembered for the real DAT. When the concentration of HCL is smaller than 1x10-7 you have to consider water! Water has a [H] of 1x10-7 and thus if you add [HCL] 1x10^-8 you actually have a combined [H] of 1.1x10^-7. the the negative log of this is just under 7 ===> 6.98.
