determine the ph of 5 grams KNO3 that is dissolved in 100ml water.KNO3 is produced by mixing .2M KOH and 0.2M HNO3...please help me...

    Actually you can pick any number you wish and that will be right. You didn't specify how much KOH is mixed with how much HNO3. ASSUMING that you have equal volumes of the acid and the base, the pH will be 7 since the nitrate ion is not hydrolyzed and neither is the K^+.

    I have these 5 chemical equations and I keep getting the same 1:1 ratio on all of them. I must be doing something wrong! KCL + NaNO3 = KNO3 + NaCl HNO3 + KOH = H2O + KNO3 H2O + SO3 = H2SO4 4Na + O2 = 2Na2O 2NO2 = 2NO + O2
