How do you tell whether a solution is basic, acidic or neutral just by looking at the formula? Like KCl. I need to know how to figure out whether it's neutral, basic or acidic and have no clue how this is done.
calculate the pH formed by mixing 100 mL of 0.20 M HCL with 50 mL of 0.30 M NaOH.
An aqueous solution is six percent by mass methanol,, and has a density = 0.988 g/mL. Determine the molarity of ethanol in the solution.
Gas Nitrous Oxide (N20) is used as an anesthetic and in aerosol cans to produce whipping cream. It is a potent greenhouse gas and decomposes slowly to N2 and O2.
A 25.0mL sample of HCl solution is titrated with a 0.139 M NaOH solution. The equivalence point is reached with 30.2 mL of base
which hydroxide precipitates first as NaOh is slowly added to the solution? b) what is the molar concentration of the first cation precipitated when the other cation just starts to precipitate out of solution?
calculate the mass of Fe(NO3)3 that you would need to yield a similar conductivity value as the NaCl
A chemist wants to prepare .50 M HCL. Commerical hydorcloric acid is 12.4 M. How many milliliters of the commerical acid does the chemist require to make up 1.50 L of the dilute acid?
What is the mass of precipitate (in Grams) that forms when 235.5 mL of 0.129 M Na2SO4 solution is reacted with excess Ba(NO3)2 solution?
a solution is made from mixing compounds A, mole fraction 0.5833, and B mole fraction 0.417. the vapor pressure of A at 55c is 95 mmHg and the vapor pressure of B at the same temperature is 42 mmHg
A weather balloon has a volume of 750 L when filled with helium at 8 oC at a pressure of 380 torr. What is the new volume of the balloon when the pressure is 0.20 atm and the temperature is -45 oC?
dissolved in water and completely neutralized by the addition of 43.70 mL of 0.303 M NaOH. Calculate the molar mass of the acid, assuming it to be a monoprotic acid.
Describe in detail how you would prepare a solution with a concentration near 0.100 M from a 0.650 M stock solution. Calculate the final concentration of the diluted solution (it won't be exactly 0.100 M). It should be within 10% of 0.100 M.
