Answer:
<u>1.4 M</u>
Explanation:
n(HBr)=3.115/81
so, 3.115/81=0.0385mol
according to the reaction, n(HBr)=n(KOH)=0.038 mol
C(KOH)=n/V=0.0385/0.02745
0.0385/0.02745 =1.4 M
in short the answer is 1.4 M (molarity)
Holy I'm not that smart lol but I'll get back to you
It is mostly used in applications that need measuring substances that would have a<span> relatively neutral pH . </span>A<span> common use is for measuring the presence of carbonic </span>acid<span> in </span>a<span> liquid. so yes its acidic</span>
Lithium is a good reducing agent because it is electropositive [it rapidly gains electrons]
fluorine is good oxidizing agent electronegative [it loses electrons fastly]
