CHÉP THIẾU ĐỀ :))
Trung hòa 100 ml HCl 1,5M thì cần bao nhiêu ml dung dịch NaOH 1M ?
bài làm :
Theo đề bài ta có : nHCl = 0,1.1,5=0,15 (mol)
Ta có PTHH :
HCl + NaOH \(\rightarrow NaCl+H2O\)
0,15mol...0,15mol
=>VddNaOH\(_{c\text{ần}-d\text{ùng}}=\dfrac{0,15}{1}=0,15\left(l\right)=150\left(ml\right)\)
Vậy..........
Cần bao nhiêu ml NaOH 1M ?
----------------------------------
\(n_{HCl}=0,1.1,5=0,15\left(mol\right)\)
Pt: \(NaOH+HCl\rightarrow NaCl+H_2O\)
0,15mol \(\leftarrow\) 0,15mol
\(V_{NaOH}=\dfrac{0,15}{1}=0,15\left(l\right)=150\left(ml\right)\)
\(n_{HCl}=0,1\cdot1,5=0,15\left(mol\right)\)
Pt : \(NaOH+HCl\rightarrow NaCl+H_2O\)
0,15 mol \(\leftarrow\)0,15mol
\(V_{NaOH}=\dfrac{0,15}{1}=0,15\left(l\right)=150\left(ml\right)\)
