The ionization constant for water $\left(K_{\mathrm{w}}\right)$ is $2.9 \times 10^{-14} \mathrm{at} 40^{\circ} \mathrm{C} .$ Calculate $\left[\mathrm{H}_{3} \mathrm{O}^{+}\right],\left[\mathrm{OH}^{-}\right], \mathrm{pH}$ , and poH forpure water at $40^{\circ} \mathrm{C} .$
$c\left(H_{3} O^{+}\right)=1.7 \cdot 10^{-7} \frac{\mathrm{mol}}{L}$$c\left(O H^{-}\right)=1.7 \cdot 10^{-7} \frac{\mathrm{mol}}{L}$$p H=6.8$$p O H=6.8$

the law. Gramma Terek. Measurement of concentration or activity off Hydro New Mayan in solution is Tom that speech? The iron product constant off water is the took is represented us kw. It is the equilibrium constant for auto ionization off water. The chemical equation represents the falling the formula for calculating the X 30 positive and which negative ion concentration is represented. The value off its three positive can be calculated as follow. After getting the value off, it's 30 positive, which turns out to be 1.71 entertains his top are minus seven. Therefore, the value off which negative will be 1.71 interdependence super minus seven AM at 40. The results is from that we can calculate the pH using formula. Their pH is a call to negative of log off X tree o positive substituting in the value we have. PH that is six point seven 670 We can find the B itch we can find the pH. That is just a simple subtraction off we can find the p. O. H. That is just a simple subtraction off 14 minus the value off pH. This turns out to be 6.7670
