) a student makes up a 0. 6 m solution of acetic acid. (note: the pka of acetic acid is 4. 74) a) what is the poh of this soluti
1 answer:
A student makes up a 0. 6 M solution of acetic acid then its pOH of this solution is 13.77
Calculation ,
A figure expressing the acidity or alkalinity of a solution on a logarithmic scale on which 7 is neutral, lower values are more acid and higher values more alkaline.
We have to find pH of the acetic acid .
[ ] = 0. 6
pH = -㏒[ ]
pH = -㏒ [ 0. 6 ]
pH = 0.22
pH + pOH = 14
pOH = 14 - pOH = 14 - 0.22 = 13.77

The "break-even" interest rate for year n that equates the return on an n-period zero-coupon bond to that of an n - 1 - period zero-coupon bond rolled over into a one-year bond in year n is defined as the forward rate.
A forward rate is a specified price agreed by all parties involved for the delivery of a good at a specific date in the future. The use of forward rates can be speculative if a buyer believes the future price of a good will be greater than the current forward rate. Alternatively, sellers use forward rates to mitigate the risk that the future price of a good materially decreases.
Regardless of the prevailing spot rate at the time the forward rate meets maturity, the agreed-upon contract is executed at the forward rate. For example, on January 1st, the spot rate of a case of iceberg lettuce is $50. The restaurant and the farmer agree to the delivery of 100 cases of iceberg lettuce on July 1st at a forward rate of $55 per case. On July 1st, even if the price per case has decreased to $45/case or increased to $65/case, the contract will proceed at $55/case.
To extract the forward rate, we need the zero-coupon yield curve.
We are trying to find the future interest rate for time period
and
expressed in years, given the rate
for
time period and rate
for time period
. To do this, we use the property that the proceeds from investing at rate
for
time period and then reinvesting those proceeds at rate
for time period
is equal to the proceeds from
investing at rate for time period
.
