а) C Na
2CH3-CH(CH3)-CH2-CH2-OH +2 Na -> 2CH3-CH(CH3)-CH2-CH2-ONa + H2
2CH3-CH(OH)-CH2-COH + 2Na = 2CH3-CH(ONa)-CH2-COH + H2
2CH3-CH2-CH2-COOH + 2Na ->2 CH3-CH2-CH2-COONa + H2
2C6H5OH + 2Na -> 2C6H5ONa + H2
C6H3(OH)(CH2-CH2OH) -> C6H3(ONa)(CH2-CH2-ONa) + H2
б) c NaOH
CH3-CH(CH3)-CH2-CH2-OH + NaOH -> CH3-CH(CH3)-CH2-CH2-ONa + H2O
CH3- CH(OH)-CH2-COH + NaOH -> CH3-CH(ONa)-CH2-COH + H2O
CH3-CH2-CH2-COOH + NaOH -> CH3-CH2-CH2-COONa + H2O
C6H5OH + NaOH -> C6H5ONa + H2O
C6H3(OH)(CH2-CH2-OH) + NaOH -> C6H3(ONa)(CH2-CH2-ONa) + 2H2O
n(CuSO4) = C*V = 2*0.5 = 1 моль
m(CuSO4) = n*M = 1*160 = 160 г
S+O2=SO2
<em>SO2</em> + H2O = <em>H2SO3</em>
H2SO3+NaOH=Na2SO3+H2O
