Acid-Base Reactions: Did the Solutions Neutralize Each Other? | Homework Help

AI Thread Summary
The discussion centers on a student's attempt to determine if a mixture of acids and bases neutralized each other. The reagents include HCl, HNO3, CaOH, and RbOH, with a focus on calculating the concentration of excess H+ or OH- ions. The student struggles with balancing the net ionic equation and receives feedback on correcting the chemical formula for calcium hydroxide. To find out if neutralization occurred, it's suggested to calculate the moles of H+ from the acids and OH- from the bases. The conversation emphasizes the importance of accurate dissociation calculations to assess the outcome of the reaction.

Homework Statement


Student mix four reagents together, thinking the solutions will neutralize each other. The solutions mixed together are 50.0mL of .1 M HCl, 100mL of .2 M of HNO3, 500mL of .01 M CaOH, 200mL of .1 M RbOH. Did the acids and bases exactly neutralize each other? If not, calculate the concentration of excess H or OH ions left in solution.

Homework Equations


M = mole/liter

The Attempt at a Solution


I looked at the solution and I understand it but I'm having trouble getting a net ionic equation.
Here is my attempt
HCl+HNO3+CaOH+RbOH>2H2O+Ca(NO3)2+RbCl
HCl+2HNO3+CaOH+RbOH>2H2O+Ca(NO3)2+RbCl
2HCl+2HNO3+CaOH+RbOH>2H2O+Ca(NO3)2+2RbCl
I can't figure out how to balance the equation to get to a net ionic equation.
Any suggestions

"CaOH" is a big mistake. You have after all written Ca(NO2)2.

One way, after you have corrected that, if you know how these things dissociate into ions, calculate how many moles of H+ are produced by that from the acids, then how many moles of OH- the bases, and decide whether these are equal, or whether one is more than the other,

Thank you :D

TL;DR Summary: cannot find out error in solution proposed. [![question with rate laws][1]][1] Now the rate law for the reaction (i.e reaction rate) can be written as: $$ R= k[N_2O_5] $$ my main question is, WHAT is this reaction equal to? what I mean here is, whether $$k[N_2O_5]= -d[N_2O_5]/dt$$ or is it $$k[N_2O_5]= -1/2 \frac{d}{dt} [N_2O_5] $$ ? The latter seems to be more apt, as the reaction rate must be -1/2 (disappearance rate of N2O5), which adheres to the stoichiometry of the...
I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
