How do I write a stoichiometric equation of the reaction between calcium hydroxide and nitric acid?
Balance mass and balance charge....
Both mass and charge are balanced.....this is simply an acid base reaction, the which we could represent as...

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.

- How many mL of NaOH are needed to neutralize the acidity in a titrated solution containing .1234 g of #AlCl_3#?
- Determine the initial pH, the pH at the midpoint (halfway to the equivalence point), and the pH at the equivalence point if 25.00mL of 0.1335 M NH3 (NH4OH) is titrated with 0.2350M HCl? Kb = 1.75*10(-5)
- A student is asked to prepare a buffer solution with pH = 8.6, using one of the following weak acids: HA (#Ka = 2.7 × 10^-3#), HB (#Ka = 4.4 × 10^-6#) or HC (#Ka = 2.6 × 10^-9#). Which acid should she choose?
- If the ratio of weak base to conjugate acid is #10:1#, to what extent does the #"pH"# change and does it increase or decrease?
- What is the pH of a buffer that was prepared by adding 3.96 g of sodium benzoate, #NaC_7H_5O_2#, to 1.00 L of 0.0100 M benzoic acid, #HC_7H_5O_2#?
