You add {eq}\mathrm{1 \ mL} {/eq} of {eq}\mathrm{.1M \ HCl} {/eq} to {eq}\mathrm{99 \ mL} {/eq} of water. What is the {eq}\mathrm{pH} {/eq} of the resulting solution? HCL: HCL is a strong acidic component. It is abbreviated as hydr...
A buffer is prepared by adding 22.0 g of sodium acetate (CH3COONa) to 520 mL of a 0.155 M acetic acid (CH3COOH) solution. Determine the pH of the buffer. The Ka of acetic acid is 1.76 x 10-5. What is the pH of a buf...
其实很简单的呀。 只要学懂一条公式便可了。 pH= -log[H+] 0.1M HCl pH= - log(0.1) = 1 1M HCl pH= - log(1) =0 NaCl is neutral so whenever it is 1M or 0.1M the pH of it is 7 CH3COOH is a weak acid the degree of dissociation of H+ ion is low (ie. it ...
Calculate the pH of a solution when 20 mL of .1 M CH3COOH (Ka = 1.76 x 10^-5) is titration with 10 and 30 mL of .1 M NaOHCalculate the pH of a solution in which 20.0 mL of 0.140 M NaOH is added to 25.0 mL of 0.140 M acetic acid.Calculate ...
In the year 1909, the chemist Søren Sørensen introduced the concept of pH from the old theories that are prevailing at that time. He also introduced the pH scale which is a breakthrough of certain theories present at that time. The negative logarithm of Hydrogen ion concentration is ...
Answer to: H2CO3 and HCO3- are used to create a buffer solution. When an acid is introduced into this buffer, which of H_2CO_3 and HCO_3^- reacts...
如果向这种混合溶液中加入少量强酸, 如盐酸(HCI.H30+),原溶液中的阴离子将和加入的酸根离子作 如下反应:H3O+CH3COO-T CH3COOH+H 20在此反应中, 产物是缓冲溶液的成分之一: 醋酸。 而如果向该缓冲溶液中加入强碱,如氢氧化钠(NaOH ),原溶液中的醋酸将和加入的氢氧根离子作如下反应:0H-+ CH3C00HTCH3C00-+...
