In 0.01 M of HCl, the concentration of the Hydronium ions is 0.01M as well since HCl is monoprotic. pH = -log [H3O+] = -log 0.01 = -log10-2 = -(-2log10) = 2 Thus, the pH of 0.01 M HCl is 2.
HCL stands for Hydrochloric acid
Molarity = moles of solute/Liters of solutionSo, get moles HCl.73 grams HCl (1 mole HCl/36.458)= 2.00 moles HCl---------------------------Molarity = 2.00 moles HCl/2 Liters= 1 M HCl=======
Na2CO3 + 2 HCl = CO2 + H2O + 2 NaCl
2 g HCl are equivalent to 0,0548 moles.

Na2CO3 + 2 HCl = CO2 + H2O + 2 NaCl
2 g HCl are equivalent to 0,0548 moles.
0.002M HCl means 0.002 moles HCl in 1L solution. Therefore 0.02 moles HCl in 10L solution. pH = 2-log2 = 2-0.3010 = 1.6990
The chemical equation is:Na2CO3 + 2 HCl = 2 NaCl + CO2 + H2O
2 Al + 2 HCl -> H2 + 2 AlCl
The reaction is:Na2S + 2 HCl = 2 NaCl + H2S
2 HCl + Pb --> PbCl2 + H2 (for Pb 2+) 4 HCl + Pb --> PbCl4 + 2 H2 (for Pb 4+)
Cu + 2 HCl = CuCl2 + H22 Cu + 2 HCl = 2 CuCl + H2
- log(0.00450 M HCl)= 2.3 pH=======
