which ones' pH value is higher? HCL or CH3COOH?

45 cm3 = 45 mL\n\n45 mL * 1.2 M HCl = 54 mmol HCl\n\n60 mL * .9M HAc = 54 mmol HAc\n\nSince the material amount is the same, HAc (acetic acid, CH3COOH) will have a higher pH because HCl is a strong acid and it will have a low pH. CH3COOH is a weaker acid, so its pH would be higher. HCl is a strong acid because the H and the Cl are strongly solvated by water molecules because of the immense polarity of the H-Cl bond. CH3COOH is weak because, while the anion is resonance stabilized, you still have a molecule with a hydrophobic end and an electron donating group. (the CH3)

its just two atoms- one hydrogen and one florine, so you have already written the molecular formula.  HF is closely related to HCl (hydrochloric acid) because Cl and F are closely related elements.  But, HCl is a much stronger acid, because it releases from H more easily than F, and HF is special in that its the only acid that can etch glass.

It also depends on if you're using a chemical indicator, or a pH probe.  When I have to dump HCl down the drain but first neutralize it with NaOH, I just use a pH probe (or occasionally litmus paper), because indicators are not readily available.

I would say CH2O2 (I'm assuming you mean formic acid, not dioxirane), CH3CO2H, and water.  \n\n"Important" is a tough word here, as all of these compounds can participate in h-bonding to varying degreees, with water being the strongest and CH2F2 being the weakest.  That said, strong hydrogen bonding gives rise to many of the nifty properties of water and in all three cases the h-bonding is powerful enough to raise the boiling points to be significantly higher than what you would expect based on molecular weight.

Well first of all you have to specify if the H's you want to account for are either comming from HCl alone or both HCl and some H's comming from the dissociation of water.\n\nI suppose that only the number of moles of H's comming from HCl is really worth while working the question for, since the H's of the dissociated water does not change the pH of the 0.10M solution.\n\nTherefore:\n\n0.10moles are in 1000mL\n? moles are in 50mL\n\n50 x 0.1 / 1000 = 0.005moles\n\nTherefore we can say that 0.005moles of HCl in 50mL of water results in a concentration of 0.10M

CH3COOH is an acid (systematic name is ethanoic acid, more commonly known as acetic acid, which is found in vinegar)\n\nSince metal + acid --> hydrogen + salt: \n2Al + 6CH3COOH --> 2Al(CH3COO)3 + 3H2

1-chloropropane, because chlorine has a higher value of electronegativity.

no, you cant.\n\nU cant even test the pH for alcohol even if it is slightly acidic compared to other organic compounds, because it's a weaker acid than water. Alcohol can dissolve in aqueous soln; they dont ionize but form network of hydrogen bonds with water molecules.\n\nIn aqueous solution, no matter how basic it is, (let's say 14, that's the best u can do) alcohol will not lose an hydrogen atom 'cause its conjugate base is a stronger base than hydroxide ions (strongest base in aqueous soln). pKa for water is 15, alcohol is 16-18.

The answer will depend on th strength of the solution. At an equal concentration,  sodium hydroxide will have a much higher pH than an solution of sodium carbonate.\n\nA 10% solution of sodium carbonate will have a much higher pH than 0.00001 M solution of sodium hydroxide.

3M it has 3 times the molarity of 1M, the 3M has 3 mols of hcl for every liter and the 1 has 1 mol for every liter and since 3 is a bigger number then one im sure u can take it from there.

A strong acid, like HCl, might cleave your ethanoic annhydride. That's the only thing I can think of. Phosphoric acid gives you a weak source of protons.

NaOH in thermometer will have chemical reaction with HCL thus the HCl temperature measured won't be accurate as chemical changes will take place. This reaction involves a base (NaOH) and an acid (HCl), so it's a neutralization reaction, which is a special type of double-displacement reaction.♥

HCL and NaOH are 'strong' acid and base. When they react, the product is neutral. NaOH + HCL --> NaCl + H2O\n\nWhat you need to find is which is the limiting reactant, the other one (what is left over) will effect the pH by its concentration in the otherwise neutral solution.\n\nFor your first problem:\n\n0.0557M HCL = 0.0557mols/liter*0.00542L = 3.02*10^(-4)mol HCL\n\n0.0377M NaOH = 0.0377mols/liter*0.00337L = 1.27*10^(-4)mol NaOH\n\n3.02*10^(-4)mol HCL - 1.27*10^(-4)mol NaOH = 1.75*10^(-4)mols HCL\n\n0.00542L + 0.00337L = .00879L\n\n[(1.75*10^(-4)mols HCL) * (1 L) ] / (.00879L) = .020M HCL\n\npH = -log(.02) = 1.70

Sulfuric acid has a higher dissociation constant than acetic acid.  This means that more of it will dissociate in solution.\nAlso, sulfuric acid has 2 hydrogen atoms  that it can give up to solution vs. 1 from acetic acid.
