The kidneys will excrete increased quantities of acid.
Explanation:
The kidneys will excrete excess H+ ions in the blood (remember H+ ions are responsible for acidity) until the acid-base balance is restored in the blood. Bicarbonates, on the other hand, will be aggressively  reabsorbed by the renal tubules as the excess H+ are being excreted. 
The acid base balance is mainly determined by the quantities of H⁺ and HCO₃⁻ ions in teh blood. These ions come from the dissociation of carbonic acid formed when carbon dioxide from tissues is dissolved in blood plasma. 
 
        
             
        
        
        
- Calcium carbonate is the  salt  among the given options.
- Calcium carbonate ( CaCO3) can be regarded as  which appears as white and odorless powder or  as a colorless crystals it is  insoluble in water. 
- The chemical  formula is  CaCO3. It can be used as an antacid as well as food colouring and a  food firming agent and a fertilizer. 
- Calcium carbonate is calcium salt as well as  carbonate salt with one-carbon compound
- Salt can be regarded as substance which is  produced by reaction between acid and  base. It  consists negative ion (anion) of that acid as well as positive ion (cation) of the base.
- Sodium hydroxide is a base and not a salt
- Carbonic acid is an acid and not a salt
- Therefore, calcium carbonate is the only salt in the among the given options.

The one that is being described above is what we call SCIENTIFIC LAW. Scientific law is what explains of what will happen every time in a certain situation. This is also different from scientific theory since scientific theory only gives an explanation to a group of happenings and this can still be modified. Hope this helps.
