Assuming the water is present at 20 °C, the solubility of barium chromate is 0.2275 mg/100 mL
Converting this to mg/L, we get:
2.275 mg/L
Converting this value again, to grams per liter, we get:
0.002275 g/L
To dissolve one gram, we require:
1/0.002275 = 439.56044
440 liters of water.
The chemical formula of a carbonate ion is CO3^2-. It is an AX3 system which means it take the trigonal planar shape. There would be two single bonds of C-O and one double bond C-O in order for C to agree with the octet rule. Two minus charges are equally distributed to the three oxygen atoms so that each oxygen of the carbonate ion would have a charge of negative 2/3.
<span>6 + x = 12. To evaluate an algebraic expression, you have to substitute a number for each variable and perform the arithmetic operations. In the example above, the variable x is equal to 6 since 6 + 6 = 12. If we know the value of our variables, we can replace the variables with their values and then evaluate the expression.</span>
A pH of 2 indicates a acid
