If acid has an H plus concentration of 1.0 x 10-4 M What is the pOH?

I advise you to first read this explanation for a better undestanding of pH of acid and base solutions.If acid has an H plus concentration of 1.0 x 10-4 M What is the pOH? The answer is at the bottom of this tutorial.pH tutorialAt 4º Celsius, density of water = 1 gram per mlOne liter of water = 1000ml = 1000 grams of waterH2O = 18 grams per mole1000 grams of water ÷ 18 grams per mole of water = 55.5 moles of water per literOf the 55.5 moles of water per liter, 10-7 moles of water split2 H2O split into Hydronium ions ( H3O+1) and Hydroxide ions ( OH-1 ) as below.2H2O(l) = H30+1 + OH-1What is really happening isWhen one water molecule picks up a positively charged hydrogen proton it momentarily becomes positively charged. The water molecule that looses the proton momentarily becomes negatively charged (the hydrogen's 1 electron remains behind). This is simulated in the animation available below:http://web.jjay.cuny.edu/~acarpi/NSC/protexch.htmThe video has one problem!The 2 H2O molecules exchange the proton when they collide with each other. After the collision, the H30+1 and OH-1 ions rapidly move away from the collision site. Thus the H30+1 and OH-1 ions that were formed from 2 H2O molecules do not reform into the same 2 H2O molecules at that site. Because of their rapid motion, they move away and find other H30+1 and OH-1 ions with which to unite.The result of this proton exchange is that at any given moment 2 water molecules out of every 1 billion are split into a positively charged H3O+1 (called hydronium) ion and a negatively charge OH-1 (called hydroxide) ion.2H2O(l) = H30+1 + OH-1The equal sign (usually a double headed arrow)is used to indicate a state of equilibrium. Chemical equilibrium is the state in which the concentrations of the reactants and products have no net change over time This means as two H2O molecules split somewhere in the container, a H3O+1 ion and a OH- ion at a different place in the container go back together. This happens due to the water molecules moving around and coming into contact with each other due to kinetic energy.In one liter of water 1.0 x 10-7 moles of waters split forming 1.0 x 10-7 moles of H3O+1 ions and 1.0 x 10-7 moles of OH-1 ions.The brackets, [ ] around the H3O+1 and OH-1 in the equations below, means moles of H3O+1 ions and moles of OH-1 ions per liter of H2O. Kw in the equations below means equilibrium constant for water.Kw = [H3O+1] * [OH-1]Since the H3O+1 ion concentration in water = 10-7 moles per liter and the OH-1 ion concentration in water = 10-7 moles per liter,Kw = [10-7(aq)] * [10-7(aq)], so Kw = 1.0 x 10-14The subscript (aq), means in a water solution.log means the exponent of 10, so -log 10-x = xpH = -log of H3O+1 concentration; pOH = -log [OH-1 ] concentrationSince [H3O+1] = 10-7, -log H3O+1] = -log 10-7 = 7pH = 7pOH = -log of OH-1 concentration; pH = -log [OH-1]Since [OH -1] = 10-7, -log [OH -1] = -log 10-7 = 7pOH = 7pH + pOH =14Solution pHFor strong acids and bases such as HCl and NaOHThe letter N represents Normality. When measuring the concentration of strong acids or strong bases, Normality means moles of H3O+1 ions or moles of OH-1 ions per liter of H2O.In 0.1 N HCl , [H3O+1] = 0.1 = 10-1, pH = 1In 0.01 N HCl , [H3O+1] = 0.01 = 10-2, pH = 2In 0.1 N NaOH, [OH-1] = 0.1 = 10-1, pOH = 1In 0.01 N NaOH, [OH-1] = 0.01 = 10-2, pOH = 2Your Question:If acid has an H plus (H+1 ion) concentration of 1.0 x 10-4 M What is the pOH?An H+1 ion can not exist, because it would be a Hydrogen atom without its electron. One H2O molecule attracts a Hydrogen proton off a second H2O molecule forming a H3O+1 ion; leaving the second H2O molecule as a OH-1 ion.This is simulated in the animation available at the website below:http://web.jjay.cuny.edu/~acarpi/NSC/protexch.htmTop of FormSince the question is concerns a 1.0 x 10-4 M solution of [H3O+1] ions, the H3O+1 concentration, [H3O+1] = 10-4pH = -log of H3O+1concentration; pH = -log [H3O+1]Since [H3O +1] = 10-4, -log [H3O +1] = -log 10-4 = 4pH = 4

Why are high and low pH materials considered hazardous?

They are considered to be highly reactive/ caustic - generally speaking a acid (<7pH) and a base (>7pH) combine together to make a relatively neutral salt (~7pH).

What is the pH of hand gel?

7ph

Ph level of distilled water?

7ph

Substance with a pH less than blood?

Well blood is a neutral which is 7pH and anything below 7pH would be an acid an a battery is an example of an acid

Who bottles water for Sprouts grocery store and what is the PH level?

7ph

Why does pure water have a 7pH value?

Because water is a neutral and high pH values are basic and low pH values are asidic.

Why don't seeds grow in soap?

Soaps are alkaline in nature and seeds grow best in 6 pH. 7 pH is neutral and more than 7pH becomes alkaline.

Do salts yield pH-values above 7?

yes.. their values vary from 2-14 on PH scale below 7pH value ones are acidic , above 7 are basic.

Is HCI a weak base?

HCL* and no, HCL (hydrochloric acid) is obviously an acid, and not a base. this is because on the pH scale HCL has a rating higher than 7pH, making it not a base nor neutral. ;)

Is pH of a river affected by pollution?

Yes, it depends on the pH of the substance polluting the river. If the substance polluting the river is an acid, then the pH will Decrease from balanced at 7pH towards 0, the most acidic. If the Solution polluting the river is basic, (bitter to the taste, slippery, probably a cleaning solution) the pH will rise toward 14.

How to convert ph to ppm?

Write an equation representing the ppm concentration: ppm = mass solute (mg) Ã· volume solution (L) Extract the data from the question: mass solute (NaCl) = 0.0045 g. ... Convert the mass in grams to a mass in milligrams: mass NaCl = 0.0045 g = 0.0045 g Ã— 1000 mg/g = 4.5 mg.

What are the common uses of a litmus paper?

The uses of litmus paper to find out the pH of solution. i.e., to check whether the solution is acidic, basic or neutral. Red litmus always turn to blue if the solution is basic. Blue litmus always turn to red if the solution acidic. They don't change their colour, if the solution is neutral. (7pH).
