Curd is not kept in copper and brass , why?

“when kept in copper or brass vessels,curd(and other acidic food items) reacts with copper and forms toxic compounds which may be unfit for human consumption,and may cause food poisoning.thus it is not advisable to keep curd and other acidic or sour food items in copper or brass vessels.”

74.4 ml of millimeters needed to react with  15 grams of baking soda

Explanation:

Given data

n C8 H8 07= 0.8 M

m NaHCO3=15 g

Solving the problem:

From the equation we get,

3x C6 H8 07 = NaHC03

Finding the molar mass for the baking soda

NaHCO3= 23+1+12+3 x16= 84 g / mol

so,

n NaHCO3= m NaHCO3/ M NaHCO3

And then,

n C6 H8 07 =1/3 × n NaHCO3

From the definition of the molarity we get

V C6 H8 O 7=n C6 H8 07/C6 H8 07

=n NaHCO3/3 × C6 H8 07 =

m NaHCO3/ M NaHCO3/ 3 × C6 H8 07

Calculating the equation we get,

V C6 H8 O 7= 15/84/3 ×0.8=5/84 ×0.8= 0.0744L= 74.4 ml

74.4 ml of millimeters needed to react with  15 grams of baking soda

n C8 H8 07= 0.8 M

m NaHCO3=15 g

Solving the problem:

From the equation we get,

3x C6 H8 07 = NaHC03

Finding the molar mass for the baking soda

Nahco3= 23+1+12+3 x16= 84 g / mol

so,

n NaHCO3= m NaHCO3/ M NaHCO3

And then,

n C6 H8 07 =1/3 × n NaHCO3

From the definition of the molarity we get

V C6 H8 O 7=n C6 H8 07/C6 H8 07

=n NaHCO3/3 × C6 H8 07 =

m NaHCO3/ M NaHCO3/ 3 × C6 H8 07

Calculating the equation we get,

V C6 H8 O 7= 15/84/3 ×0.8=5/84 ×0.8= 0.0744L= 74.4 ml
