Answer:
A titration is a technique where a solution of known concentration is used to determine the concentration of an unknown solution. Typically, the titrant (the know solution) is added from a buret to a known quantity of the analyte until the reaction is complete
Answer:
Sodium-calcium exchanger on the sarcolemma
Explanation:
The sodium-calcium exchanger which is an antiporter membrane protein, removes calcium from cells. The energy of the electrochemical gradient of sodium is used by allowing it to flow down its gradient while moving across the plasma membrane
The product formed when benzene reacts with isobutyl chloride in the presence of AlCl3 is tertiary butyl benzene.
THE CHEMICAL REACTION AS
step 1 : CH₃ - CH - CH₂Cl + AlCl₃ → CH₃ - CH₂ -CH₂ - CH₂⁺ + AlCl⁻
step 2: CH₃ - CH₂ - CH₂ - CH₂⁺ ---H SHIFT--→ (CH₃)₃C⁺
PRODUCT
C₆H₆ + (CH₃)₃ C⁺ → C₆H₆ ( CH₃)₃ C⁺
Hence the product formed is tertiary butyl benzene.
